It would have been helpful if you had sent your R code of how you
constructed the sab object.
If you have a data.frame, the subset command you are having trouble with
should work fine. See below.
# Working Example
sab = data.frame(group=c('Group A', 'Group A', 'Group C', 'Group B', 'Group
C'), gender=c(1,1,1,2,2))
subset(sab, sab$group=='Group A')
Perhaps your data is stored as a matrix? If so, the following code will fail
with the error message you experienced.
# Non Working Example
sab2 = matrix(c('Group A', 'Group A', 'Group C', 'Group B', 'Group
C',1,1,1,2,2),5,2)
subset(sab2, sab2$group=='Group A')
