Hi,
Just to add:
If the columns are not in the order (Mood1:Mood10) in the dataset.
mood<- data.frame(Mood2=6:10,Mood1=1:5,Mood10=11:15,Mood3=16:20)
do.call(cbind,lapply(names(mood),function(i)
mood[i]*as.numeric(gsub("\\D+","",i

Hi - I am having trouble installing rpy2. I have already compiled R as a
shared library, but I do not have admin privileges on so I am trying to

pip install -user rpy2
but I am getting the following error:
./rpy/rinterface/_rinterface.c
What is the purpose of the variable R_HOME? What value should I set it to?
Thanks,
