Hi, have anybody a hint how i could avoid the cumbersome way (..especially the value part) change the data representation from n column data.frame to an stacked representation. many thanks Christian #example data dfw <- as.data.frame(matrix(runif(10*10),ncol=10)) dfw$group <- sample(c("X","Z"),nrow(dfw),replace=T,prob=c(0.75,0.25)) # change var <-

Hello, Have anybody a hint, how I could iterate over the vector below. So I'll wish only 8 iterations. Put the "range vector" in c() didn't help. for(i in c(1,2,3,4,5,11:20,21:50,51:100)) { sum(dfc[i,"cnt"]) # or similar actions } Thanks in advance Christian
