------------------------------

NEW FUNCTIONS ADDED:
  * as.ym() adds a yearmonth class for extracting dateparts and adding months.
  * as.Date.ym() converts a yearmonth to a date.
  * NALevel() allows to quickly define an alternative level for NAs in a factor.
  * CutAge() is a convenient wrapper for cutting age variables in slices 
    of e.g. 10 years.

UPDATED FUNCTIONS:
  * Year(), Month() now also extract the parts from a yearmonth representation.
  * Hodges-Lehman now uses long-longs instead of integers, allowing larger vectors.
  * AddMonthsYM() has been integrated in AddMonths(). Use AddMonths(as.ym(202402)) 
    instead.
  * The Desc() procedure now puts the response in columns instead in rows as up to now
    in the case of two factor variables. So the resulting table is transposed compared
    to before.
  * The Desc() procedure for 2x2 tables includes a confidence interval for 
    the difference of proportions based on BinomDiffCI(..., method="mn").

BUGFIXES:
  * The documentation of RelRisk() did not correspond to the code.

    As a replacement for this, there is a argument std_est with 
    which the method specific non-standard point estimator can be returned.
    (Thanks to julienbio99, MrJerryTAO and Vilmantas for the
    research and discussion)

UPDATED FUNCTIONS:
  * CochranArmitageTest has been updated to use scores instead of ordinal values only.

    instead of c("two.sided", "increasing", "decreasing"), which were poorly defined.
  * BoxedText gains a formula interface.  
  * RevCode takes dots now, for reverse numeric codes.

    meaning within the function body. 
  * PlotCorr() now displays the matrix in the same form, as it is defined.

    which was documented, but not implemented.
  * PlotCorr() mislabeled the legend when breaks were specified (Credits for the
    fix to Duncan Murdoch).  
  * Several replacements of T with TRUE, which have apparently always 
    slipped through until now. (Again, the credit goes to Duncan Murdoch.)

  * MeanCIn() gives the required samplesize to obtain a confidence interval 
    of a given width.
  * Rank() is added at the expense of DenseRank() using a fast implementation in 
    data.table, that allows ranking based on multiple columns. 
  * %::% does the same as %:% but in greedy mode, say using the last match instead

  * StrExtractBetween() would have rejected to extract parts between two identical
    characters.
  * Quantile(), and in consequence Median(), would not have treated missings correctly.

    "fmt", which allows to define formats for counts, numbers, percentages 
    AND p-values.
  * SplitPath() gets a further information "fullpath".  
  * StrTrunc() gets two new arguments "ellipsis" and can truncate strings
    on word boundaries with "useWordBoundaries".

BUGFIXES:
  * Cramer's V bias correction is corrected (hmm...).
  * TMod() supports single models now.




DescTools 0.99.31 (2019-12-21)
------------------------------

NEW FUNCTIONS ADDED:
  * WrdUpdateFields() can be used to update fields in a Word document.
  * Mgp() does the same for axis title, labels and line as Mar() does
    for the margins.
  * PlotPairs() is a more specific pairs() variant.

DEPRECATED:
  * PlotDev() X was both a desperate and unsuccessful attempt to rid the analysis
    code of superfluous technical reporting code. The new approach uses meta-code
    together with ToWrdWithBookmark(), which does not require any changes to 
    the original code. As a result, PlotDev() has been removed.

    (which is likely to be remarkable for a numeric variable).

BUGFIXES:
  * PseudoR2() will work with negative binomial models again.
  * Untable would not have returned the expected results in some combinations 
    of column names. (Credits to Vilmantas Gegzna for detecting this issue)
  * Desc() would not have handled unnamed lists. (Again Vilmantas noticed this)

    temporarily set options.
  * With SaveAs() it's possible to save an R object under a different name.
  * Quot() calculates successive divisions in the same way as diff() does with 
    successive differences.

  * PseudoR2() is using reformulate() instead of update() in order to improve
    interoperability within the tidyverse, especially support tibbles created

    have been transferred to the package DescToolsAddIns, as these functions
    presumably only make sense in a GUI context.
  * IsValidWrd() has been replaced by IsValidHwnd(), which can be used to 
    generally check Windows handles (at least for Office applications).

DescTools 0.99.24 (2018-03-19)
------------------------------

NEW FUNCTIONS ADDED:

  * Append() is used to append elements to a vector, rows/columns to a matrix
    and columns to a data.frame in the in the same sense as append().
  * Add some new univariate parametric extreme value distributions with their
    distribution, quantile and density functions.

BUGFIXES:
  * identify.formula() would have omitted NAs while preparing the model.frame
    and so might have returned wrong rownumbers. It will now by default pass
    NAs if the argument has not been set.
  * Gmean will return 0 if any element of x is zero now.
  * Desc.character would not have passed the plots when output to MS-Word.

DEFUNCT:
  * InsCol() and InsRow() have been condensed into Append(), which is more
    general and more flexible.
  * PlotMatrix() has not been used and was obsolete.



DescTools 0.99.23 (2017-12-11)
------------------------------

NEW FUNCTIONS ADDED:
   * TTestA() will calculate a Student t-test using given sample statistics

   * PlotBinTree() would not have placed the text correctly in the horizontal
     representation.
   * Str() would not have passed ... args to str, as stated in help.

   * Freq() would not have calculated percentages, when NAs were to be included
     and a userdefined order was desired.

DEFUNCT:
   * Date() was needless, as ISODate does the same job.
   * Exec(x), consisting out of eval(parse(text=x)) did not contain enough
     functionality to justify an own function.
   * Same applies to AddClass() and RemoveClass().
   * ClipToVect() read the clipboard and printed the enquoted content.
     This operation is implemented in DescToolsAddIns::Enquote() resulting in
     a more usable approach.
   * LogLin() has been integrated in LogSt() with an option for the base.
   * LogGen is not needed anymore.
   * SetRowNames(), SetColNames() have been condensed into SetNames().

     have changed the column order.
   * Vignettes had not been compiled by v.0.99.20.

DEFUNCT:
   * StrRep() does not offer more functionality than strrep() and has
     therefore been removed.

------------------------------

NEW FUNCTIONS ADDED:
   * VonNeumannTest() testing for the randomness of a sequence has been added.

     because of the named argument. (Credits to Tomas Kalibera)
   * TOne() would have mixed up footnote signs for numeric tests.
   * Hmean() returned 1/mean(x) instead 1/mean(1/x) since 0.99.18. (Credits to

     Daniel Wollschlaeger)
   * Desc data.frame displayed a title with multiple lines for long definitions.




DescTools 0.99.18 (2016-11-04)

   * HosmerLemeshowTest used for testing glms has been integrated.
   * GeomTrans() can be used to transform a geometric structure by translating,
     scaling and rotating.
   * Basic linear modeling functions VIF() and StdCoef() have been added.


UPDATED FUNCTIONS:
   * Numerous updates in help files.
   * digits argument is now passed through to Format.
   * Desc.data.frame now makes use of the new function Abstract() instead
     of old str() for giving the initial overview.

   * Trim will not longer return a sorted vector. The indices of the trimmed values
     will now be returned in an attribute "trim".
   * Rotate accepts xy.coords and returns the same class (instead of a list).
   * Rotate will choose the centroid of the given polygon instead of the fixed
     point (0,0) and gets a new argument allowing to define the aspect ratio.
   * DrawRegPolygon returns a xy.coords object instead of a list.
   * PlotLinesA will use lines instead of usr coordinates for placing the
     legend text. The distance of line segements can now be controlled in more
     detail.
   * DescToolsOptions have been fundamentally reorganized, as they were grown
     organically and organized chaotically (for not saying: not organized at all ...).
     See ?DescToolsOptions for all the details.
     "fixedfont" must now be defined as list, "footnote", "col" are now vectors instead
     single values and formats (fmt) are organized as list. (see also new function Fmt()).

   * Hmean() and Gmean() get an option for calculating confidence intervals.
   * lines.Lc for plotting Lorenz curve gets a CI-option.
   * StrDist gets an ignore.case argument.
   * Functions using ConDis for calculating concordant discordant pairs, as

     with a O(n log(n)) implementation (as long as no CIs are needed).
   * IsDichotomous gets a new argument strict for checking for strictly two levels
     and a na.rm argument, which is set to FALSE by default.


BUGFIXES:
   * PairApply simply overwrote the diagonal with 1, which was inappropriate.
     Functions are now also evaluated for diagonal elements.
   * TOne would not have displayed column names, in case there were only
     boolean variables in the data.frame to describe. (credits to Beat Bruengger)
   * CombN used a wrong formula for the number of permutions with no
     repetitions respecting order. (credits to Carlos Redondo-Figuero)
   * PlotDot erroneously reversed the order of datapoints, when simultaneously
     supplied with group data and error bars.
   * TOne would not have displayed variables with just one unique value.

DEFUNCT:
   * The data.frame interface for Label was ambiguous. A data.frame is now
     treated like any other object.
   * SetLabel made no longer sense, since Label and `Label<-` had been defined.
   * ImportDlg has been renamed to FileOpenCmd as it had nothing to do with import
     of data.
   * WrdText has definitely been replaced by ToWrd.
   * WrdR has always been a code study and has been removed.
   * PlotHorizBar has been removed. barplot can do everyhing it could...

     now be FALSE by default.
   * PlotFdist gets a new argument args.curve.ecdf allowing to superpose
     a function to the ecdf-plot.
   * PlotFdist's default argument for the bw of the density curve changes to
     bw = "SJ", which turns out to be the better default for n < 1000.
   * Large and Small have been recoded in C++ (thanks to Nathan Russel) to run
     faster and get a renamed argument (na.last instead of na.rm).
     So far they are supposed be the fastest on the market...
   * PartCor has been renamed to CorPart, as it can be better found with that name.
   * Format gets a new format code "eng" for engineering format.
   * StrDist gets an additional method "normalized levensthein".
   * PlotMultiDens gets an additional parameter fill for coloring the areas.
   * PlotWeb gets a lwd argument for defining freely the lined widths.
   * In Recode the argument newlevels is replaced by the dots argument. This
     is the same rationale as in Rename.
     *** This change has the potential to break existing code, I apologize! ***
   * Numerous updates in help files.

BUGFIXES:
   * Desc for variables with only one value won't raise an error any more.
   * Conf for rpart will find the reference now.

     arguments are now being recycled.
   * RoundM has been renamed to RoundTo.
   * PlotRCol has been renamed to ColPicker and gets a new argument "locator".
   * Desc has been conceptually rewritten to follow clearer S3 class design and
     to be more consistent in the arguments (while improving performance).
     A print and a plot method are now available. PlotDesc(x) has
     therefore been replaced by plot(Desc(x)).
     (I fear this has the potential to break your code, I apologise for that ...)
   * The class interfaces .default, .formula etc. are by default not exported anymore.
     This applies to the function PageTest, LeveneTest, JonckheereTerpstraTest,
     CochranTest, HotellingsT2Test, DunnTest, DunnetTest, MosesTest, NemenyiTest,
     PostHocTest, YuenTTest, ZTest, SignTest, RunsTest, ScheffeTest,
     MeanDiffCI, Format, Label, Rev, Sort, PercTable, Lc, EtaSq, PlotArea,

     handle groups correctly.
   * Hmean reported an error, when supplied with a NA vector, instead of simply
     returning NA and shut up.
   * Desc.numeric would not always have sorted the whole vector, which in some cases
     resulted in incorrect unique and extreme values.
   * StrAlign would not alwas have trimmed white space on the right side.

KNOWN PROBLEMS / TODOS:
   * Leading zeros and big.mark can not be used together in Format.
   * DoCounts should get an O(n log(n)) implementation, containig std. errors.
   * We have not reached our goal yet - documentation is still not finalized, some functions
     not tested thoroughly enough, others have rather a proof of concept status -
     but we are well on our way to achieving it. Systematic check over all
     function interfaces, ensuring consistency with R-standards and DescTools
     conventions will be performed next.
