hi, I have a question about merging two files.
For example, I have two files, the first file is like the following:
id trait1
110.2
211.1
39.7
610.2
78.9
10 9.7
11 10.2
The second file is like the following:
idtrait2
1 9.8
2 10.8
4 7.8
5 9.8
6 10.1
Try the merge function
?merge
in1 = "id trait1
110.2
211.1
39.7
610.2
78.9
10 9.7
11 10.2

in2 = "id trait2
1 9.8
2 10.8
4 7.8
5 9.8
6 10.1

1310.1

data1 = read.table(textConnection(in1), header=T)
data2 = read.table(tex
