6.8 Length of String

20180606 The tidy way to get the length of a string is stringr::str_length().

str_length("hello world")
## [1] 11
str_length(c("hello", "world"))
## [1] 5 5
str_length(NULL)
## integer(0)
str_length(NA)
## [1] NA

The function base::nchar() is the traditional approach.

nchar("hello world")
## [1] 11
nchar(c("hello", "world"))
## [1] 5 5
nchar(NULL)
## integer(0)
nchar(NA)
## [1] NA
