Subject: Bug running pbinom() in R-GUI?
Today I was running a graduate level stats lab using R and we encountered a
major problem while using the current build of the Cocoa GUI:
>From the GUI:
> system.time(pbinom(80, 1e5, 806/1e6))
[1] 14.37 4.94 30.29 0.00 0.00
>
>From the command line on the same machine:
> system.time(pbinom(80, 1e5, 806/1e6))
[1] 0.02 0.00 0.02 0.00 0.00
>
I've tried the CRAN version and the latest build of the R-GUI and both
deliver the same terrible performance. It seems as if this only occurs for
certain arguments, but we saw this on ~15 different machines today. And it
seems to only be when running the Cocoa GUI. No problems at all with this
under Windoze. Any ideas?
