I am a student from Liverpool UK, working with some genetic data using R.
I got a data.frame with about 250.000 rows and using a for loop to delete
certain rows using the following code:
x <----- is a data.frame
x = x[-5,] ---> deletes row 5
x = x[-10,] ---> delets row 10
x = x[-i,] --> deletes row i
This takes ages for some reason. Isnt there a quicker way to do this?!
