CRdata vs. Cloudnumbers
Cloudnumbers and CRdata are two new cloud computing services. I tested the two services with a very simple script. The script simply creates a dataframe of 10000 numbers via rnorm, and assigns them to a factor of one of two levels (a or b). I then take the mean of the two factor levels with the aggregate function. In CRdata you need to put in some extra code to format the output in a browser window....
