Suppose you're given a data frame in R and asked to find the maximum or minimum value in each column or row. How would you do this?
- Use the apply() function with the appropriate margin argument and the max() or min() function
- Use the max.col() or min.col() function for data frames
- Use the apply() function with the appropriate margin argument and the max_row() or min_row() function
- Use the max() or min() function with the appropriate argument and the apply() function
To find the maximum or minimum value in each column or row of a data frame in R, you can use the apply() function with the appropriate margin argument (1 for rows, 2 for columns) and the max() or min() function. This combination allows you to apply the max() or min() function across the specified dimension and obtain the desired results.
