Does rpart package have some requirements on the original data set?
...the majority of y is 1 (information in the data set is small),
rpart automatically regards it as already a single class and therefore
won't proceed any further. If this understanding is correct, what I
should do if I still want rpart to do something on this data set?
Thanks a lot!

Graphically show population density for a specific geographic area using R
...to the shapefile (.shp)? I mean how to
link a population density to its corresponding zip code area?
4. Finally, how could I use intensity of colors to show the differences
in the population densities?
I would greatly appreciate it if someone could provide me a simple
example. Thanks a lot!
