How to Trim a String in R ?

To trim a string in R, you can use the trimws() function.

In this example,

We assign a string value of " Hello World " to the variable str1.
We then use the trimws() function on str1 to remove leading and trailing whitespace characters.
Finally, we print the trimmed string.

str1 <- "   Hello World   "
trimmedStr1 <- trimws(str1)
cat('Trimmed string is: ', trimmedStr1, '\n')

Trimmed string is: Hello World

In this example,

We assign a string value of " apple" to the variable str2.
We then use the trimws() function with the which parameter set to left to remove leading whitespace characters.
Finally, we print the trimmed string.

str2 <- "   apple"
trimmedStr2 <- trimws(str2, which = 'left')
cat('Trimmed string is: ', trimmedStr2, '\n')

Trimmed string is: apple

In this example,

We assign a string value of "banana " to the variable str3.
We then use the trimws() function with the which parameter set to right to remove trailing whitespace characters.
Finally, we print the trimmed string.

str3 <- "banana   "
trimmedStr3 <- trimws(str3, which = 'right')
cat('Trimmed string is: ', trimmedStr3, '\n')

Trimmed string is: banana
