Hi,
I'm trying to install Chipster (for microarray analysis:
http://chipster.csc.fi/), which expressly relies on R 2.6.1 (for now).
So I'd like to install automatically (i.e. using a 'install.packages'
like function) the last version of a package compatible with the running
R version.
For example, when I'm running R-2.6.1 and want to install package 'lme4'
I get the following warning:
In install.packages("lme4", repos =
contrib.url("http://cran.r-project.org";)) :
package ‘lme4’ is not available
Also:
available.packages(contriburl =
contrib.url("http://cran.r-project.org";)) does not return any line for
package lme4.
This is because the latest version of package lme4 on CRAN depends on R
2.9.0. However there is older versions stored on CRAN that are
compatible with R version 2.6.1 (in subdirectory contrib/Archive/lme4).
Is there a script/package out there that does the trick, retrieving the
list of the older versions and download the latest version compatible
with R 2.6.1?
Thanks
