...t have been a joy to see all the nice (and not so nice) graphs that were shown. As an exercise, I recreated the map shown on the NY-Times website [ http://www.nytimes.com/packages/khtml/2004/11/03/politics/ 20041103_px_ELECT_GRAPHIC.html ] If you're interested, http://www.ai.rug.nl/~hedderik/R/US2004 contains the created maps, the data and the code. Note that there are some differences in the R map and the NYT map (most notably with respect to some missing data in some New England states, some mismatches in county names, and the representation of NYC), but I was quite satisfie...

...(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 (http://www.ai.rug.nl/~hedderik/R/US2004/map.r ) ? I have geographic (e.g. country, state, county, zip code) count data in a data frame that I would like to represent on a map, but still need to study how map.r works, especially the map.center function...

...e } apply(data,1,recode) I don't get what I want, because dataline$var1 always evaluates to NULL. Is is at all possible to use the $xxx method of refering to columns when using apply? And if not, is there another way by means of which I can use column names instead of numbers?

I use AfterStep on Linux. I made an R.xpm file (attached) and put this icon in the "wharf". To invoke R I click on the R icon. I did not find an offical R.xpm, and so I am submitting this one for your collective consideration.... The idea behind the icon is that it looks like a scatterplot, which is "statistical". My main beefs with my R.xpm are that it doesn't have a

Thanks to Martin Maechler, Douglas Bates, Peter Dalgaard, and Hedderik van Rijn for pointing out the problem is with the color resource demands of the two applications and for their suggested possible solutions.

I think I'm missing something tonight in the usage of 'legend': plot(0, type="n") legend(locator(1), month.abb[1:5], pch=15, col=1:5) gives me something similar to what I want. But legend(locator(1), month.abb[1:5], fill=T, col=1:5) gives me 5 black boxes. What am I doing wrong? Thank you, > version _ platform i686-pc-linux-gnu arch i686 os

For numbers ending in 5 Excel always rounds up and I want to reproduce this in R rather than use the round function. I have tried: x<-as.integer(x*100+0.5)/100 and x<-floor(x*100+0.5)/100 However, some values of x cause problems e.g x<-floor(4.145*100+0.5)/100 4.14 I have tried breaking it down into steps and force the results to 10 significant figures in the following function,
