Help a nublet brother out. 😀
I failed to see where and how ada comes up with the correct formula to use when you simply used the words "model.formula" as the parameter for the ada formula? I was expecting to see the dependent response over the explanatory variables? Some how, from what you've got there, it figured out the last vector in the frame was the response? Unless you declared model.formula in code somewhere outside of what you posted? I also don't understand why there's the creation of two empty data frames, which go terminally unused, stuck between two identical runs of the ada model on the same training data? I suspect this is a mis-paste, especially since one of the data frames starts out uncharacteristically with a capital letter, which falls out of the naming convention used elsewhere, and we know R is strictly case sensitive. So confused. :w00t:
On another note, I regularly use RODBC to get to my SQL Server data. Is there any particular benefit to using the rsqlserver package vs the other? If it's anything like other interfaces, there may be some syntactical benefits?
Was thrilled to see this article on here today. We need more merging of the SQL Server and R communities.
