Hello,
You need to use,
subset(vef1,vef1$edad1==0)
That should not be necessary (and quite defeats the usual value of
subset()'s nonstandard evaluation):
> vef1<-read.table(text="
+ age edad1
+ 12 1
+ 10 0
+ 9 0
+ 14 1
+ 15 1
+ ", header=TRUE)

age edad1
2 10 0
3 9 0

vef1<-read.table(text="

subset(vef1,vef1$edad1==0)

Subject: [R] Subset data
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
