Re: [R] transpose but different

Try this. First we use outer to form a matrix such that i,j-th entry is TRUE if i, j are in the same group and unequal and FALSE otherwise. We apply which on the rows of that matrix to get the groups that are associated with the row group. We then cbind the components together using ts class to

[R] transpose but different

Hi all, I want to make extra columns in my datafile where the id of every groupmember is mentioned in separate columns. To explain it better see the example: id<-c(1,2,3,4,5,6,7,8,9,10,11,12) group<-c(1,1,1,1,2,2,3,3,3,3,3,3) a<-as.data.frame(cbind(id,group))
