Subject: Re: [R] Comparing 2 different files in R
This is not an area I am going to be able to help with but we still need a lot
more information I think.
At the moment we know nothing about the structure of the data, what you are
trying to accomplish, in substantive terms, and what you may have tried. As I
say. I know nothing about the area but perhaps we need to know if all you want
is to see if the SNP's are the same in different files, do you need summary
stats or graphics. Come to think of it, something like a journal abstract might
do nicely.
It may be that more knowlegeable people can recommend useful approaches or
suggest that your type of analysis is more suitable in the Bioconductor lists.
Ideally we should see any 'minimal' code you may have written in R if any, &
some sample data is possible. See ?dput for a handy way to provide data but we,
hopefully, don't need to see 8mg of data. Probably just the first few lines of
data would do. A command like dput(head(50)) should be enough. See ?dput
and?head for what these are doing or have a look at the links provided earlier.
For various reasons dput() is about the best method available for passing data
to a help list or forum.
Oh and one more thing. You seem to have sent this last post in HTML. The R-help
list is plain-text so we would ask that you send everything in plain. HTML is
stripped away and the resulting plain text can be so close to unintelligible
that many readers will just ignore it.
==============================================
Thanks and sorry for being light on detail.
I have multiple files of raw human genome SNP data. Very large - the compressed
zip files are about 8mb large.

Probably but since you have not told us anything about what you are
