[R] "Warning message: package '...' was built under R version 2.3.0"

[Tuszynski, Jaroslaw W.]

I do have single version of R (2.2.0) and all packages I have were installed
by downloading precompiled packages from PA or NC repositories within last
month. 

I also just managed to download 'modeltools' from PA2 and its DESCRIPTION
says:
Built: R 2.3.0; ; 2005-11-04 20:47:47; windows

R console:

	> utils:::menuInstallPkgs()

	trying URL

	In addition: Warning message:
	package 'modeltools' was built under R version 2.3.0 
	Error: unable to load R code in package 'modeltools'
	Error: package/namespace load failed for 'modeltools'

The same package downloaded from PA1 does not give me any warnings or
errors.

I have just downloaded
http://www.ibiblio.org/pub/languages/R/CRAN/bin/windows/contrib/2.2/mvtnorm_
0.7-2.zip
and its DESCRIPTION file correctly has:
"Built: R 2.2.0; i386-pc-mingw32; 2005-10-14 14:44:12; windows"


My guess is that you are using one library for two different R versions 
and you have installed some R-devel package into the library you are now 
using with R-2.2.0 ...

You cannot mix binary packages for R < 2.3.0 with those for R-devel due 
to changes in environment handling.
