Greg, I tried installing v2.5 using the instructions on R-forge but ran into
errors:
> install.packages("TeachingDemos", repos="http://R-Forge.R-project.org";)
Warning: unable to access index for repository
http://R-Forge.R-project.org/bin/windows/contrib/2.10
Warning message:
In getDependencies(pkgs, dependencies, available, lib) :
package ‘TeachingDemos’ is not available
Looked like some dependency was not being found. Somehow I determined it
might be a missing tcl/tk-related package (don't remember how), so I did
this:
> library("tcltk")
Loading Tcl/Tk interface ... done
> lattice.demo(x,y,z)
Error in structure(.External("dotTclObjv", objv, PACKAGE = "tcltk"), class =
"tclObj") :
[tcl] floating point value is Not a Number.
So it got further but still not there. Any ideas?
BTW, I'm using R 2.10 on Windows.
Thanks,
Doug
