Subject: [R] How to split DF int
Hello,
I'm trying to split my DF into a list using incremental loop. How can
I avoid NULL elements in this list?
DF <- data.frame(var1 = 1:10, var2 = 11:20, var3 = 21:30, var4 = 31:40)
x <- list()
i <- 1
while (i <= ncol(DF)-1) {
x[[i]] <- DF[, i:c(i+1)]
i <- i + 2
}
x
Many
