Thomas Lumley recommended the same thing last night. I have just finished debugging the routines and validating them for use without NAs. I had to fix a number of typos in my code for the other functions but now they all work properly. I still need to test, debug, and validate them for use of NAs with na.rm set to both true and false.

Once I have validated them (ie. that they return the exact same things as unlist(lappy(split(x,i),FUNCTION)) does), I will get together an external package and make it available on CRAN.

I am in the stupid position of knowing how to add the functions internally to R with no problems, but I still have to learn how to build and add external packages.

So something else to learn!
