Write.table Question
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 Le 8/1/2011 17:18, Margaux Keller a ?crit :
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?
