[R] Does the perl language have an equivalent to browser?

[Andrew Perrin]

I don't know exactly what browser() does, but when you run perl -d use the
c command to follow through the script:

c <linenumber> # continue until reaching line <linenumber>

Or, set one or more breakpoints:
b <linenumber>
b <sub name>

and then use:

c

to continue to the next breakpoint.

Use d to delete a breakpoint.

Answers to this and much more can be found using perldoc perldebug.
