Re: [R] Simple loop question

Here're a couple alternatives if you want to use the index instead of the variable name: # Reproducible data frame a1 <- 1:15 a2 <- letters[1:15] a3 <- LETTERS[1:15] a4 <- 15:1 a5 <- letters[15:1] df <- data.frame(a1, a2, a3, a4, a5) df # a1 a2 a3 a4 a5 # 1 1 a A 15 o # 2 2 b B 14
