The str_trim function in R is used to remove leading and trailing whitespace from a string. This function is particularly useful when working with data that may contain unnecessary spaces, as it allows for a cleaner and more efficient manipulation of the data. To use the str_trim function, simply specify the string you wish to trim as the first argument, and the direction of the trim (either “both”, “left”, or “right”) as the second argument. Additional options include the characters to be trimmed, as well as the encoding of the string. Below are some examples of using the str_trim function in R:
– str_trim(” Hello World “) would return Hello World”
– str_trim(” Hello World “, side = “left”) would return Hello World ”
– str_trim(Hello World”, side = “right”, chars = “ld”) would return Hello Wor”
– str_trim(” Hello World “, side = “both”, chars = c(H”, “d”)) would return “ello Worl”
Overall, the str_trim function is a useful tool for cleaning and manipulating string data in R.
Use str_trim in R (With Examples)
The str_trim() function from the package in R can be used to trim whitespace from a string.
This function uses the following syntax:
str_trim(string, side = c(“both”, “left”, “right”))
where:
- string: Character vector
- pattern: Side on which to remove whitespace
The following examples show how to use this function in practice
Example 1: Trim Whitespace from Left Side
The following code shows how to use the str_trim() function to trim whitespace from the left side of a string:
library(stringr)
#create string
my_string <- " Hey there everyone. "
#view string
my_string
[1] " Hey there everyone. "
#create new string with white space removed from left
new_string <- str_trim(my_string, side="left")
#view new string
new_string
[1] Hey there everyone. "
Notice that all of the whitespace on the left side of the string has been trimmed.
Example 2: Trim Whitespace from Right Side
The following code shows how to use the str_trim() function to trim whitespace from the right side of a string:
library(stringr)
#create string
my_string <- " Hey there everyone. "
#view string
my_string
[1] " Hey there everyone. "
#create new string with white space removed from right
new_string <- str_trim(my_string, side="right")
#view new string
new_string
[1] " Hey there everyone."
Notice that all of the whitespace on the right side of the string has been trimmed.
Example 3: Trim Whitespace from Both Sides
The following code shows how to use the str_trim() function to trim whitespace from both sides of a string:
library(stringr)
#create string
my_string <- " Hey there everyone. "
#view string
my_string
[1] " Hey there everyone. "
#create new string with white space removed from both sides
new_string <- str_trim(my_string, side="both")
#view new string
new_string
[1] Hey there everyone."
