Removing the last character
To remove the string’s last character, we can use the built-in substring() function in R.
The 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 last character t from the month string:
month = 'august'result = substring(month,1, nchar(month)-1)print(result)
Output:
"augus"
In the above example, we have passed the 1, nchar(month)-1 as a second and third arguments to the substring() function. so it begins the extraction at position 1 and extracts before the last character position (5) of a string.
The nchar() function is used to caluclate the length of a string in R.
