In this tutorial, we are going to learn about how to remove the first character of a string in the R language.
To remove the string’s first character, 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 character
j from the
month = 'july' result = substring(month, 2) print(result)
In the above example, we have passed the
2 as a second argument to the

substring()function doesn’t mutate the original string.
Similarly, we can also use the
stri_sub() function from the
