Taking Input from User in R Programming - GeeksforGeeks

Last Updated : 07 Jul, 2021 Summarize Comments Improve Developers often have a need to interact with users, either to get data or to provide some sort of result. Most programs today use a dialog box as a way of asking the user to provide some type of input. Like other programming languages in R it’s also possible to take input from the user. For doing so, there are two methods in R.Using readline() methodUsing scan() methodUsing readline() methodIn R language readline() method takes input in string format. If one inputs an integer then it is inputted as a string, lets say, one wants to input 255, then it will input as “255”, like a string. So one needs to convert that inputted value to the format that he needs. In this case, string “255” is converted to integer 255. To convert the inputted value to the desired data type, there are some functions in R,as.integer(n); —> convert to integeras.numeric(n); —> convert to numeric type (float, double etc)as.complex(n); —> convert to complex num...
