Hi,
Have you read the documentation for merge? The relevant section says
" If 'all.x' is true, all the non matching cases of 'x' are appended
to the result as well, with 'NA' filled in the corresponding
columns of 'y'; analogously for 'all.y'."
Please do get in the habit of reading the documentation before posting
on the mailing list.
Best,
Ista
