Description Usage Arguments Value Examples
When the debug package is in step-mode, there are a few special system functions that it can either step into, or leave the system to handle en bloc. These functions all have expression-type arguments. Currently, they are: try
, suppressWarnings
, eval
, evalq
, and (for built-in methods only) with
and within
. The step-into behaviour is controlled by calling step.into.sysfuns
, which operates like par
. You can also circumvent step-into at particular lines, by using go(n)
to zoom through to the next statement. Additional methods for with
and within
can be handled via e.g. mtrace( with.myS3class)
, so are not considered "special" here.

tag-value pairs of logicals, e.g. |
Either the previous value(s) of tags that are set, or the entire logical vector of tags.
