How do you delete a row in R?

To remove the rows in R, use the subsetting in R. There is no built-in function of removing a row from the data frame, but you can access a data frame without some rows specified by the negative index. This process is also called subsetting. This way, you can remove unwanted rows from the data frame.

What is a loop in R?

How do you get input in MATLAB?

x = input( prompt ) displays the text in prompt and waits for the user to input a value and press the Return key.
