I'm not sure if this is an Rgui issue or Mac only issue, or an R 3.0.0 RC
problem, or a problem with the pkg. I'll start here.
I am updating my package ChemoSpec to work with R 3.0.0 With the following
sessionInfo I can install the old version of ChemoSpec from a CRAN repos and it
works fine:
[R.app GUI 1.60 (6457) x86_64-apple-darwin10.8.0]
> sessionInfo()
R version 3.0.0 RC (2013-03-27 r62426)
Platform: x86_64-apple-darwin10.8.0 (64-bit)
Now I have an updated local source package of ChemoSpec which builds and checks
fine. If I install it via the gui or command line, I can do
library("ChemoSpec") just fine. But if I do ?ChemoSpec, R or Rgui just wanders
off with the pinwheel of death and must be force quitted. That's not the best
clue. If I do sessionInfo() before library("ChemoSpec") sessionInfo() works
fine. If I do sessionInfo() after library("ChemoSpec"), R or Rgui crashes. I
suspect it might be Rgui as because the crash occurs the moment I type the
first '(' so it seems to occur when the gui is adding the ')' - notice that the
crash info is printed before my sessionInfo command is echoed to the gui. The
crash report is below. Suggestions most appreciated. Bryan
