ub-group by the two variables I have selected.
I was wondering why this new script worked.
Kind regards,

Yes. In particular:
data$variable==1 & data
makes no sense (data is a data frame). A typo perhaps? Or as Richard
indicated, consult references/tutorials to learn proper syntax for
(vectorized) predicates.

"The trouble with having an open mind is that people keep coming along and
I think the syntax you are looking for is
datasubset <- data[ data$A ==1 & data$B == 1 , ] )
This gives the subset of your original data for variable A with value
1 and variable B with value 1.
