Hi,
I was borrowing someone's code today, and they were using the package
DiagnosisMed. I downloaded the package using the built-in package
installer in the GUI (R 2.12.1 running on Mac OS 10.6.5). The package
manager lists the following information: ‘DiagnosisMed’ version 0.2.3
Every time I attempted to load the package, I subsequently had R hang.
The same commands which would cause the hanging after loading the
package worked without a hitch when I didn't load the package.
Actually, after I wrote that last sentence I tried starting R from
scratch, loading the package, and then typing 2+2.
This was my result:
> library(DiagnosisMed)
Loading required package: epitools
Loading required package: TeachingDemos
Loading required package: tcltk
Loading Tcl/Tk interface ...
> 2+2
Loading required package: tcltk

lib.loc)
10: .getRequiredPackages2(pkgInfo, quietly = quietly)
11: library(DiagnosisMed)
Possible actions:
1: abort (with core dump, if enabled)
2: normal R exit
3: exit R without saving workspace
4: exit R saving workspace
I have a workaround. But I just thought I'd report it anyways.
