r - Split a string every 5 characters

Question

Suppose I have a long string:

"XOVEWVJIEWNIGOIWENVOIWEWVWEW"

How do I split this to get every 5 characters followed by a space?

"XOVEW VJIEW NIGOI WENVO IWEWV WEW"

Note that the last one is shorter.

I can do a loop where I constantly count and build a new string character by character but surely there must be something better no?

Answer 1

Using regular expressions:

gsub("(.{5})", "\1 ", "XOVEWVJIEWNIGOIWENVOIWEWVWEW")
# [1] "XOVEW VJIEW NIGOI WENVO IWEWV WEW"
