How to Fix the Error:

This error can be eliminated by using the select() function directly from the dplyr package.

Example:

R

# R program to demonstrate how to  
# fix the error 
  
# Importing libraries 
library(dplyr) 
library(MASS) 
  
# Determine the average mpg grouped by 'cyl' 
mtcars %>% 
  dplyr::select(cyl, mpg) %>% 
  group_by(cyl) %>% 
  summarize(avg_mpg = mean(mpg)) 

Output:

Interpretation: The code compiled successfully without any error because dplyr explicitly uses the select() function in the dplyr package rather than the MASS package.

How to Fix: Error in select unused arguments in R?

In this article, we will be looking toward the approach to fix the error in selecting unused arguments in the R programming language.

Error in selecting unused arguments: The R compiler produces this error when a programmer tries to use the select() function of the dplyr package in R provided that the MASS package loaded. R tries to make use of the select() function from the MASS package instead when such an error takes place. This article focuses on how to fix this error.
