Ok, so I'm new to R, but this is driving me crazy. In this example, I am trying to process each element in a list.
<code> s = "1,2" l = strsplit(s, ",", fixed=TRUE) print("BEGIN") n = length(l) i = 1 while (i <= n) { x = l[[i]] print(paste("x:", class(x), x)) print("BEFORE PRINT") print(x) print("AFTER PRINT") i = i + 1 } </code> <actual output> [exec] [1] "BEGIN" [exec] [1] "x: character 1" "x: character 2" [exec] [1] "BEFORE PRINT" [exec] [1] "1" "2" [exec] [1] "AFTER PRINT" [exec] [1] "END" [exec] [1] TRUE </actual output> <expected output> [exec] [1] "BEGIN" [exec] [1] "x: character 1" [exec] [1] "BEFORE PRINT" [exec] [1] "1" [exec] [1] "AFTER PRINT" [exec] [1] "x: character 2" [exec] [1] "BEFORE PRINT" [exec] [1] "2" [exec] [1] "AFTER PRINT" [exec] [1] "END" [exec] [1] TRUE </expected output> What *basic* concept am I missing here? The same thing happens with for (x in l) and lapply(l, function(x) print(x)).
