[R] Subset data

[antonio.bso...@sapo.pt]

Hi 
Need a little help. This is easy question, but i´m new to R.
I want to subset a data frame called vef1 using a variable that is a factor 
called edad11, 0 if under 11 years, 1 otherwise.
I tried:
vef1.sub<-subset(vef1, edad11==0)
The code runs correctly but i get a empty dataframe.
If i use this code in Deducer everything is OK.
Can you help me?
Thanks in advance

Thanks to all
The problem is fixed. What happened is that i was using the epicalc library and 
this way the program didn´t find the var edad11.
Switching off epicalc everything is all rigth.
Thanks again
