[R] Subset data

[Ista Zahn]

Hi Antonio,

It's hard to know for sure what the problem is, because we don't know
what your vef1 data.frame contains. My guess is that edad11 is not
numeric, so never equals 0 (although it might equal the character
string "0").

If you paste the results of str(vef1) in your reply we can see if my
guess is correct.

Best,
Ista
