hi,
I have determined some of my own answers, so will share here.
There are binary associations within the R libraries specific to the
environment
that created them, be it Windows or Linux, 32 or 64 bit. I found these
associations in the
Meta directory of the libraries. So, R libraries cannot be shared across
different
platforms as I had hoped as R libraries have a binary component.
As for samr, and some of the other Linux packages available, these packages
must first be
compiled by R, which in so doing produces the 'missing' Meta directory,
among other
critical output.
The procedure I used for Linux was to download a package, for example samr.
I then extracted its contents, which produced a 'samr' directory.
I changed to that directory and, from a command line, issued the following:
#R CMD INSTALL -l samr samr
This compiles the directory (last argument) into the library samr (first
argument),
the best that I can determine anyway.
The result was yet another samr directory containing all of the expected
contents, including the
Meta directory, under this one.
I copied this samr directory to:
/usr/lib64/R/library
...and repeated these steps for the 'impute' library, apparently needed by
samr, and
then tried again to run the developer's software (I didn't write it) and it
worked.
So, Im up and running on 64-bit Linux and R / samr.
Maybe these steps are not the best, but they worked for me.
Hope this helps any other newbies out there : )!
