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

You can also use a sub-string without a loop. substring is the vectorized substr

x <- "XOVEWVJIEWNIGOIWENVOIWEWVWEW"
n <- seq(1, nc <- nchar(x), by = 5) 
paste(substring(x, n, c(n[-1]-1, nc)), collapse = " ")
# [1] "XOVEW VJIEW NIGOI WENVO IWEWV WEW"
