Dear R-sig-Mac'ers: I'm posting on behalf of a student who is having trouble with accessing the help files in R.app (I think) on MacOS X.4 (I think X.4.11?) . The basic symptom is that in a clean R session she gets results like this:
> ?plot
Error in file(out, "wt") : cannot open the connection
This is generic (i.e. happens with any help request). After a bit
more poking around we triggered
2010-02-09 15:20:21.010 R[16728] *** Exception handlers were not
properly removed. Some code has jumped or returned out of an
NS_DURING...NS_HANDLER region without using the NS_VOIDRETURN or
NS_VALUERETURN macros.
R(16728,0xa000ed88) malloc: *** error for object 0x3b610038:
Non-aligned pointer being freed
R(16728,0xa000ed88) malloc: *** set a breakpoint in szone_error to
debug
R(16728,0xa000ed88) malloc: *** Deallocation of a pointer not
malloced: 0x41d60; This could be a double free(), or free() called
with the middle of an allocated block; Try setting environment
variable MallocHelp to see tools to help debug
We have both tried searching/googling for this particular problem,
without success -- found a fair amount about issues with help.start()
when running firewalls, but nothing that seemed to match our situation.
* Does this ring any bells for anyone? Have we missed something
obvious (I hope)? What are the next steps in the
diagnostic/troubleshooting pathway?
* Is there a searchable version of the R-sig-mac archives?
Rsitesearch doesn't seem to offer it, and the R-sig-mac archives seem to
be available only month-by-month (& not searchable), as far as I can tell.
thanks,
Ben Bolker
