[R] load ing and saving R objects

[Richard Mott]

Does anyone know a way to do the following:

Save a large number of R objects to a file (like load() does) but then 
read back only a small named subset of them . As far as I can see, 
load() reads back everything.

The context is:

I have an application which will generate a large number of large 
matrices (approx 15000 matrices each of dimension 2000*30). I can 
generate these matrices using an R-package I wrote, but it requires a 
large amouint of memory and is slow so I want to do this only once.  
However, I then want to do some subsequent processing, comprising a very 
large number of runs in which small  (~ 10) random selection of matrices 
from the previously computed set are used for linear modeling.  So I 
need a way to load back named objects previously saved in a call to 
save(). I can;t see anyway of doing this. Any ideas?

Thanks
