US county map question
Hi R-help:
I'm just an old guy and new to this list... But have been using R for
years now.
I want to make a map of counties in the US with shaded colors that
depend on the level of variable "Y" that I want to map.
I have the US county and state fips codes and the Y variable.
How do I do this?
Please reply to pzs6@cdc.gov
Thanks,

state map question
Hi R-Help:
I want to produce a map of the US with different colors for selected
states.
I installed the map package, and then used:
library(maps)
I can see that by using
map( 'state' )
you get the state boundaries, also.
How do I fill in different colors for the different states? I see there
is a col parameter for map, but can't see how to get it to work!
Please reply

question about boxplot
Here is a question from an old guy:
I want to use the boxplot function as follows:
boxplot( p.prop ~ R + bins )
This command makes nice boxplot for the factor "R" crossed with the factor "bins".
I am having alot of trouble getting control of the labels on the X axis. I want to control it more by specifying what the labels are, controling the 'size' of those

difference between 2 dates: IN MONTHS the way Mothers compute it
Hi R-people:
I need a function to compute the number of months between 2 dates, in the same way a mother would do it.
For example, if a kid is born on February 6, the number of months between that date and March 7 is exactly 1 month, although it is only 29 days.
Thank you!

[LLVMdev] ldc (LLVM backend for the D Programming Language) has x86-64 support
Hello everyone,
I just thought I would let people here know that ldc (llvm backend for the D
Programming Language) is getting pretty usable (a few larger libraries
compile) and it now has x86-64 support added. I decided to run some timings
on some D and C++ code to compare ldc to dmd (the mainline compiler), gdc
(the gcc based D compiler) and g++. I used a ray tracing program found in
