For years I have been using options(error = recover) either in .Rprofile or
from within R for debugging purposes. The functionality of this appears to
have changed and I can't recover it (no pun intended) using the ?options
help page. How can I get the old functionality back, particularly from
within .Rprofile? A specific line entry would be appreciated. An example,
the help page, and sessionInfo() follow. Thanks, Mark
b.func <- function(x) {y <- x + 2; nonsense; y}
> b.func(3)
Error in b.func(3) : object 'nonsense' not found ## in the past this would
be a menu with numbers for what level I want to go to (in this case just 1)
This help page states:
'error': either a function or an expression governing the handling
of non-catastrophic errors such as those generated by 'stop'
as well as by signals and internally detected errors... The
functions 'dump.frames' and 'recover' provide alternatives
that allow post-mortem debugging. Note that these need to
specified as e.g. 'options=utils::recover' in startup files
such as '.Rprofile'.
