Selecting specific columns using dplyr package by column index
In this approach to select the specific columns of the given data frame, the user needs first install and import the dplyr package in the working R console of the user and then call the select function and pass the index of the required columns as the argument of this function
Syntax:
data_frame %>% select(column_index_1,column_index_2,...)
R
# Importing dplyr library library ( "dplyr" ) # Creating DataFrame gfg < - data.frame (a= c (5, 1, 1, 5, 6, 7, 5, 4, 7, 9), b= c (1, 8, 6, 8, 6, 7, 4, 1, 7, 3), c= c (7, 1, 8, 9, 4, 1, 5, 6, 3, 7), d= c (4, 6, 8, 4, 6, 4, 8, 9, 8, 7), e= c (3, 1, 6, 4, 8, 9, 7, 8, 9, 4)) # Selecting specific columns using dplyr # package by column index gfg %>% select (2, 4, 5) |
Output:
