[R] program never enters browser mode when I add browser()

[Joshua Wiley]

Hi Michelle,

In addition to Jeff's advice, can you now reproduce the original
error?  What you are describing is highly improbable if everything is
properly executed.  It becomes more likely if more was chagned between
running than just inserting browser().  For example, if you reran/had
made changes in other code you forgot to run and then sourced that
into R in addition to having added browser() to bigfunction.  If
browser() was really run, it should have come up, perhaps somewhere in
.... is something made the function return a value and terminate or
your code is written in such a way that the portion that browser() was
in was not run.

Right now this is all just speculation, further help will really
require more details to work with.

Cheers,

Josh
