Hi Margaux,
Check the row.names and col.names arguments of write.table.
See ?write.table
write.table (dat, file = "/path/to/my/data.txt", sep = " ",
col.names=FALSE, row.names=FALSE)
HTH,
Ivan

Hi,
I'm trying to create an abbreviated data file from a larger version. I can
use the subset command to create a value for this data:
dat<-subset(raw.data, select=c(SNP, Pvalue))
head (dat)
SNP Pvalue
1 rs11 0.6516
2 rs12 0.3311
3 rs13 0.5615
but when I try to write.table using:
write.table (dat, file = "/path/to/my/data.txt", sep = " ", col.names=NA)
I end up with a file that looks like this:
"" "SNP" "Pvalue"
"1" "rs11" 0.6516
"2" "rs12" 0.3311
"3" "rs13" 0.5615
when what I want is something that looks like this:
rs11 0.6516
rs12 0.3311
rs13 0.5615
What should I be including?
Thanks,
Margaux
