How to remove the first n characters of a string in R
In this tutorial, we will learn how to remove the first n characters of a string in the R language.
Removing the first n characters
To remove the string’s first n characters, we can use the built-in
substring() function in R.
substring() function accepts 3 arguments, the first one is a
string, the second is start position, third is end position.
Here is an example, that removes the first 3 characters from the
month = 'august' result = substring(month, 4) print(result)
In the example above, we have passed the
4 as a second argument to the
substring() function. so it starts the extraction at position
2 and extracts the remaining part of the string.
nchar() function helps us to caluclate the length of a string in R.
Note: The substring() function doesn’t modify the original string.
