R Programming: Remove the variables 'Solar.R' and 'Wind' from airquality

R Programming: Data frame Exercise-26 with Solution

Write a R program to call the (built-in) dataset airquality. Remove the variables 'Solar.R' and 'Wind' and display the data frame.

Sample Solution :

R Programming Code :

data = airquality
print("Original data: Daily air quality measurements in New York, May to September 1973.")
print(data)
data[,c("Solar.R")]=NULL
data[,c("Wind")]=NULL
print("data.frame after removing 'Solar.R'  and 'Wind' variables:")
print(data)

Sample Output:

[1] "Original data: Daily air quality measurements in New York, May to September 1973."
