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? I hope someone can help
