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?

Answer 1

No *apply stringi solution:

x <- "XOVEWVJIEWNIGOIWENVOIWEWVWEW"
stri_sub(x, seq(1, stri_length(x),by=5), length=5)
[1] "XOVEW" "VJIEW" "NIGOI" "WENVO" "IWEWV" "WEW" 

This extracts substrings just like in @Jilber answer, but stri_sub function is vectorized se we don't need to use *apply here.
