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
