[R] .Rdata questions

I have no direct answer to Lorenz's problem.

On a related note, though, I was unable to "source" a large matrix that I
had "dumped".  I kept running out of cons memory (the maximum of which
seems to be 1000000).  When I recalculated the matrix and used write to
create a file, thought, I was able to read it in using read.table.  I hope
this saves someone the frustration of having to discover that.
