Dear R-users,

I have the following 2 files;

A

V1 V2

A      1
A      2
A      3
A      4
B      1
B      4
C      1
C      3
D      4

B

V1                V2
process1       1
process2       2
process3       3
process4       4

I want to get this output

C

V1    V2     V3
A      1       process1
A      2       process2
A      3       process3
A      4       process4
B      1       process1
B      4       process4
C      1       process1
C      3       process3
D      4       process4


I want to compare A$V2 with B$V2, if it is the same, then append B$V1 to A.

Any tips are highly appreciated. TQVM!
