Great idea and something that will definitely be highly used (I'm downloading it now!), but I really would be cautious attempting to provide what R provides, 'but better'.

R's power comes from the fact that hundreds of scientists have written packages for it when they have a new method - you won't be able to get that overnight. Also, R has strong links with other languages like C.

Finally, while I agree that sometimes R's syntax can be slightly obfusicated, I don't really think the examples on their site are fair... You can 'plot(y~x)' guys :p
