Using the substr() function
We can get the first character of a string by using the built-in substr() function in R.
The substr() function takes 3 arguments, the first one is a string, the second is start position, third is end position.
Here is an example, that gets the first character g from the color string:
color = 'green'firstCharacter = substr(name,1,1)print(firstCharacter)
Output:
[1] "g"
In the above example, we have passed the 1 , 1 as second and third arguments to the substr() function. so it begins the extraction at index position 1, ends at index position 1.
Note: The substr() function doesn’t mutate the original string.
