## Environment Browser

## Usage

    browser()

## Value

A call to `browser` causes a pause in the execution of the current expression and runs a copy of the R interpreter which has access to variables local to the environment where the call took place. Local variables can be listed with `ls`, and manipulated with R expressions typed to this sub-interpreter. The interpreter copy is exited by typing `c`. Execution then resumes at the statement following the call to `browser`.

Typing `n` causes the step-through-debugger, to start and it is possible to step through the remainder of the function one line at a time.
