R Programming: Order the dataset airquality entire data frame by the first and second column
R Programming: Data frame Exercise-25 with Solution
Write a R program to call the (built-in) dataset airquality. Check whether it is a data frame or not? Order the entire data frame by the first and second column.
Sample Solution :
R Programming Code :
data = airquality
print("Original data: Daily air quality measurements in New York, May to September 1973.")
print(class(data))
print(head(data,10))
result = data[order(data[,1]),]
print("Order the entire data frame by the first and second column:")
print(result)
Sample Output:
[1] "Original data: Daily air quality measurements in New York, May to September 1973." [1] "data.frame" Ozone Solar.R Wind Temp Month Day 1 41 190 7.4 67 5 1 2 36 118 8.0 72 5 2 3 12 149 12.6 74 5 3 4 18 313 11.5 62 5 4 5 NA NA 14.3 56 5 5 6 28 NA 14.9 66 5 6 7 23 299 8.6 65 5 7 8 19 99 13.8 59 5 8 9 8 19 20.1 61 5 9 10 NA 194 8.6 69 5 10 [1] "Order the entire data frame by the first and second column:" Ozone Solar.R Wind Temp Month Day 21 1 8 9.7 59 5 21 23 4 25 9.7 61 5 23 18 6 78 18.4 57 5 18 ........... 119 NA 153 5.7 88 8 27 150 NA 145 13.2 77 9 27
