Hello, 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 etc... This takes ages for some reason. Isnt there a quicker way to do this?!
