It's all about memory. In your first example, you are trying to create a data frame with 20 columns and 54 billion (thousand million) rows. Just to store this amount of data as an array of doubles you would need 8 terabytes of memory. You are being a bit optimistic trying to do it with only 500 Megabytes. Martyn
