R Programming: Extract 3rd and 5th rows with 1st and 3rd columns from a given data frame
R Programming: Data frame Exercise-7 with Solution
Write a R program to extract 3rd and 5th rows with 1st and 3rd columns from a given data frame.
Sample Solution :
R Programming Code :
exam_data = data.frame( name = c('Anastasia', 'Dima', 'Katherine', 'James', 'Emily', 'Michael', 'Matthew', 'Laura', 'Kevin', 'Jonas'), score = c(12.5, 9, 16.5, 12, 9, 20, 14.5, 13.5, 8, 19), attempts = c(1, 3, 2, 3, 2, 3, 1, 1, 2, 1), qualify = c('yes', 'no', 'yes', 'no', 'no', 'yes', 'yes', 'no', 'no', 'yes') ) print("Original dataframe:") print(exam_data) print("Extract 3rd and 5th rows with 1st and 3rd columns :") result = exam_data[c(3,5),c(1,3)] print(result)
 "Original dataframe:" name score attempts qualify 1 Anastasia 12.5 1 yes 2 Dima 9.0 3 no 3 Katherine 16.5 2 yes 4 James 12.0 3 no 5 Emily 9.0 2 no 6 Michael 20.0 3 yes 7 Matthew 14.5 1 yes 8 Laura 13.5 1 no 9 Kevin 8.0 2 no 10 Jonas 19.0 1 yes  "Extract 3rd and 5th rows with 1st and 3rd columns :" name attempts 3 Katherine 2 5 Emily 2
