I have a problem with reading a file data.txt that has a header Each row has the individual ID and then some data that are letter and numbers such as 00 If I read the file as
data<-read.table("data.txt",sep='\t', header=T) write.table(data,file="data1.txt", sep='\t', quote=F, col.names=T, row.names=F) data1.txt looks different than data.txt. In data1.txt some of the 00 entries are replaced with just a 0! But If I read the file as data<-read.table("data.txt",sep='\t', header=F) write.table(data,file="data2.txt", sep='\t', quote=F, col.names=F, row.names=F) Then data2.txt looks exactly like data.txt (no problem) My problem is when I need to merge data with another data set for example data3, How can I telll R to merge them If I specify the header=F, I tried M<-merge(data, data3, by”V1”) This does not work. What is the problem?
