Using R, getting a “Can't bind data because some arguments have the same name” using dplyr:select

Question

#use readtable to create data frames of following unzipped files below
x.train <- read.table("UCI HAR Dataset/train/X_train.txt")
subject.train <- re         


        

Answer 1

This error is often caused by a data frame having columns with identical names, that should be the first thing to check. I was trying to check my own data frame with dplyr select helper functions (start_with, contains, etc.), but even those won't work, so you may need to export to a csv to check in Excel or some other program or use base functions to check for duplicate column names.
