Substring() function in R is widely used to either extract the characters present in the data or to manipulate the data. You can easily extract the required characters from a string and also replace the values in a string.
Hello folks, hope you are doing good. Today let’s focus on the substing function in R.
Substring: We can perform multiple things like extracting of values, replacement of values and more. For this we use functions like substr() and substring().
substr(x,start,stop) substring(x,first,last=1000000L)Where:
x = the input data / file. Start / First= starting index of the substring. Stop / Last= Ending index of the substring.Well, I hope that you are pretty much clear about the syntax. Now, let’s extract some characters from the string using our substring() function in R.
#returns the characters from 1,11 df<-("Journal_dev_private_limited") substring(df,1,11)Output = “Journal_dev”
#returns the characters from 1-7 df<-(...
