Check, what "cols" is. This warning may be obtained, if
"cols"
is a character value. For example

  cols <- "a"
  paste("V", 1L:cols, sep = "")

  Error in 1L:cols : NA/NaN argument
  In addition: Warning message:
  In paste("V", 1L:cols, sep = "") : NAs introduced by
coercion

What is the relationship of this to the command above?

If you include a reproducible example, you have a better chance
to get a useful answer.
