Wrap a character string in R, we will explore how to use the str_wrap function in R to wrap a character string into nicely formatted paragraphs.

This function is part of the stringr package, which provides a variety of functions for working with strings.

Wrap a character string in R

To demonstrate the usage of str_wrap, we will create a character string x and install/load the stringr package:

x <- "heyho I am a very long string"
install.packages("stringr")
library("stringr")

Example 1: Wrapping a Character String with str_wrap

We can use the str_wrap function to wrap our character string x into nicely formatted paragraphs.

We can specify the maximum width of each line by providing an integer value as the second argument:

str_wrap(x, 10)

This will output a wrapped character string with each line limited to 10 characters:

# "heyho\nI am a\nvery long\nstring"

As you can see, the str_wrap function has inserted newline characters (\n) into our character string, resulting in well-formatted paragraphs.

Example 2: Wrapping with Multiple Line Breaks

We can also use the str_wrap function to wrap our character string with multiple line breaks.

For example, we can specify the number of line breaks by providing an integer value as the second argument:

str_wrap(x, 3)

This will output a wrapped character string with three line breaks:

# "heyho\nI am a\nvery long\nstring\n"

As you can see, the str_wrap function has inserted multiple newline characters into our character string, resulting in well-formatted paragraphs.
