I'm using the gsummary function to calculate a sum of V1 (column one) from my data 'mytest' by group (V2,or column 2). If V1 (the variable of interest) is all the same value (in this case all 2's), I do not get back the correct summation. If there is at least one difference in V1 (all 2's except for one 1), it gives me correct values. So either I am doing something wrong or there is a bug in the gsummary function. # Incorrect sums mytest <- as.data.frame(matrix(c(2,rep(2,8),1,1,2,2,2,3,3,3,3),ncol=2)) mytest gsummary(mytest,form=V1~1|V2, FUN=sum)[,1] # Correct sums mytest <- as.data.frame(matrix(c(1,rep(2,8),1,1,2,2,2,3,3,3,3),ncol=2)) mytest gsummary(mytest,form=V1~1|V2, FUN=sum)[,1] ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
