[R] problems with reading the data and merge

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
write.table(data,file="data1.txt", sep='\t', quote=F, col.names=T,
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
write.table(data,file="data2.txt", sep='\t', quote=F, col.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
How can I telll R to merge them If I specify the header=F,
M<-merge(data, data3, by”V1”) This does not work.
What is the problem? I hope someone can help
