crowding/stacktrace: Dump the context stack

The function stacktrace() dumps R's current context stack into a data frame. This stack may be somewhat different from the various fictions constructed by sys.* functions. Since this package inspects data structures that are not exported parts of R's API, it may be unstable or need tweaking to work on your system.
