How to Remove All Whitespace Characters from a String in R - Step by Step Examples

How to Remove All Whitespace Characters from a String in R ?

To remove all whitespace characters from a string in R, you can use the `gsub` function with a regular expression pattern.

In this example,

We create a string variable str with a value of "Hello World".
We then use the gsub function with a regular expression pattern "\\s" to replace all whitespace characters (including tabs, spaces, newlines, etc.) with an empty string in str.
Finally, we print the modified string str.

str <- 'Hello World'
modifiedStr <- gsub('[[:space:]]', '', str)
print(paste('Modified string:', modifiedStr))
