如何找到字符串的长度在 r？

Question

How to find the length of a string (number of characters in a string) without splitting it in R? I know how to find the length of a list but not of a string.

And what about Unicode strings? How do I find the length (in bytes) and the number of characters (runes, symbols) in a Unicode string?

See ?nchar. For example:

> nchar("foo")
[1] 3
> set.seed(10)
> strn <- paste(sample(LETTERS, 10), collapse = "")
> strn
[1] "NHKPBEFTLY"
> nchar(strn)
[1] 10
