Drop multiple columns by using the column name
We can remove a column with select() method by its column name
Syntax:
select(dataframe,-c(column_name1,column_name2,.,column_name n)
Where, dataframe is the input dataframe and -c(column_names) is the collection of names of the column to be removed.
Example: R program to remove multiple columns by column name
R
# load the library library(dplyr) # create dataframe with 3 columns id, # name and address data1=data.frame(id=c(1,2,3,4,5,6,7,1,4,2), name=c('sravan','ojaswi','bobby', 'gnanesh','rohith','pinkey', 'dhanush','sravan','gnanesh', 'ojaswi'), address=c('hyd','hyd','ponnur','tenali', 'vijayawada','vijayawada','guntur', 'hyd','tenali','hyd')) # remove name and id column print(select(data1,-c(id,name))) # remove name and address column print(select(data1,-c(address,name))) # remove all column print(select(data1,-c(address,name,id))) |
