Iterating over characters of string R

Question

Could somebody explain me why this does not print all the numbers separately in R.

numberstring <- \"0123456789\"

for (number in numberstring) {
  print(num         


        

Answer 1

Just for fun, here are a few other ways to split a string at each character.

x <- "0123456789"
substring(x, 1:nchar(x), 1:nchar(x))
# [1] "0" "1" "2" "3" "4" "5" "6" "7" "8" "9"
regmatches(x, gregexpr(".", x))[[1]]
# [1] "0" "1" "2" "3" "4" "5" "6" "7" "8" "9" 
scan(text = gsub("(.)", "\\1 ", x), what = character())
# [1] "0" "1" "2" "3" "4" "5" "6" "7" "8" "9"
