Dear all,
I hope this message finds you well. I am currently trying to subset my data by
two variables, so far, I have tried two different ways to stratify participants
into groups. I would like to use the �summary� and �table� arguments to
characterise the data of participants based on the presence of two variables
and summarise this sub-set against a third variable.
I have used this method:
dgb001<-subset(data,data$variable==1 & data,data$variable)
However, I get the following error: �Error: cannot allocate vector of size 16.0
Gb�. Is there another method I can try?
Kind regards,
