I have a data that contains 15 rows by 4 columns, does anyone know how to delete every rows except row number 5, 10 and 15?
Figure below shows the input data, the whole highlighted rows would be the rows that I want to retain, in other words, I would like to delete row from 1 to 4, 6 to 9 and 11 to 14. Any help would be appreciated a lot, thanks in advance!
