52000, or I am a moron

So in doing my thesis, I have more than 52,000 slots in my data set. As you can imagine, most of those are blank. However, to run some of the tests, I have to fill in all the slots, which means that I have to fill my data set with zeroes.

Last night I tried and tried to figure out a way to put those zeroes in more than 1 at a time. I could not figure it out.

So I spent HOURS entering zeroes by hand. My hands were killing me. My head was hurting from annoyance.

This morning, one of the PhD students responded to my plea for help on facebook.

The answer: Copy the zero and highlight a bunch of slots and paste.

Which is about as basic as you can get. I am such a moron.
