How to remove first character of a string in R
In this post we will give you information about How to remove first character of a string in R. Hear we will give you detail about How to remove first character of a string in RAnd how to use it also give you demo for it if it is necessary.
we are going to learn about how to remove the first character of a string in the R language.
Removing the first character
To remove the string’s first 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 first character j from the month string:
month = 'july'result = substring(month, 2)print(result)
Output:
[1] "uly"
In the above example, we have passed the 2 as a second argument to the substring() function. so it begins the extraction at index position 2, and extracts the remaining part of the string.
Note: The substring() function doesn’t mutate the original string.
Similarly, we can also use the stri_sub() function from the stringi package.
Example:
stri_sub(month,2)
