RandomForest, Party and Memory Management
...of the data set, I have often memory problems (in
particular with the Party package; RandomForest seems to use less memory).
I really have two questions at this point
1) Please see how I am using the Party and RandomForest packages. Any
comment is welcome and useful.

Automatted Getter/Setter
...ough a process when read in and read out to add/remove commas
(between every three numbers) to make them more readable.
The getter I currently have is like this:
def sale_price
Listing.insert_commas(read_attribte (:sale_price))
end
and the setter is:
def sale_price=(price)
write_attribute(:saleprice, Listing.remove_commas(price))
end
The trouble is there is at least 5 other fields that need the same thing
done for them (and most likely more will be added in time). I was
wondering if there is some way I could do this more automatted like:
:attr_reader :sale_price, ...., ...., ....
Any hel...
