Selecting specific Columns Using Base R by column index
In this approach to select the specific columns, the user needs to use the square brackets with the data frame given, and. With it, the user also needs to use the index of columns inside of the square bracket where the indexing starts with 1, and as per the requirements of the user has to give the required column index to inside the brackets
Syntax:
data_frame
R
# 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 Base R # by column index gfg[ c (2, 4, 5)] |
Output:
b d e
1 1 4 3
2 8 6 1
3 6 8 6
4 8 4 4
5 6 6 8
6 7 4 9
7 4 8 7
8 1 9 8
9 7 8 9
10 3 7 4
