It wasn't the merge command. It doesn't create the
variable x3.

This is what I need, but my dataframe has many rows and
it returns to me the
following message:
Error: cannot allocate vector of size 120 Kb
In addition: There were 18 warnings (use warnings() to
see them)
Assuming that its the merge command that generated the
error try this
sqldf instead of the merge line:
library(sqldf)
sqldf("select * from x, y using(k1, k3)", dbname =
tempfile())
You can also try it without dbname = tempfile() but that
has a higher
chance of overflowing memory.
See http://sqldf.googlecode.com for more info on sqldf.
