global variable - @@var
I tried to keep track of the number of access to a specific controller.
I declared ''@@mycount = 0'' in the controller class. The methods in the
controller will increment the @@mycount (@@mycount = @@mycount + 1) and
print the value to the html page and show in the browser. The value is
always 1, no matter how many times I access the controller and its
action(s). Is this not t...

Next Record
Okay, I know this will probably be a very easy question. But I am
discovering that RonR makes just about everything easy. The problem is,

Help with maps
A few questions about maps...
(1) How can I find a listing of the internal data sets that map() from the maps library contains?
For example, "usa", "county", "state", "nz" all work. Are there any others?
(2) Is there an easier, more generalized way to produce this (http://www.ai.rug.nl/~hedderik/R/US2004/ ) type of plot than this
