[R] Use dump or write? or what?

[Matt Curcio]

Greetings all,
Thanks for all your help so far.
Let me give a better idea of what I am doing.  I have hundreds of
files that I need to plow thru with a t-test and correlation test.
BTW, 'tempA' and tempB' are simply columns of numbers from a gene-chip
experiment that spits out dna 'amounts'. So I have set up a loop to
read the files and carry out the tests but need to save it for later
inspection (and Jim H-you are probably right, for later inspection).
By inspection I mean I don't know what I want to do with it yet,
Remember: "That's why they call it Research."

So it seems that 'save/load' might be a good alternative for my work.
Any suggestions,
M
