...through an apply call. Example: a= array(1:100, dim = c(17,2)) RollingAverage(a[, 1], 7) # works fine apply(a, 2, RollingAverage) # this doesnt work as it doesnt see RollingObs Is there a way to pass an additional parameter to apply?

Does anyone know what the units are for projected coordinates obtained using mapproj's mapproject function with an Albers projection? Thanks for any and all help!

Hi list, I have a real problem with plotting US state map. When I try to plot the northern state, there will be some blank space in the top of graph (see case 1 example), and when I plot southern states, there will be a blank space in the bottom of plot (see case 2). I spent almost 2 days to figure out a solution, but could not. Would you help me if you know what the problem is? Regards, Alireza

R users, In S, there was a function called usa() that would draw the map of the United States, plus it had other options for graphics. I have looked but I can't find the equivalent in R. Is there one? Thanks, Jason

My version does not do projections or thinning but will accept the standard S[-Plus] database files (*.[GLN]).

R gurus, On Aug 20, 2002, I asked in R-help about calculating a running 5-day median on a large matrix. Thanks to Martin Maechler <maechler@stat.math.ethz.ch> and Ray Brownrigg <Ray.Brownrigg@mcs.vuw.ac.nz> for responding. I ended up writing C code (and an R interface) to do it, which is about 1000x faster than the naive method! (72s became .09s on a 223 x 520 matrix). I added a running mean function too, which is very simple and is about 15x faster than apply(.....

hi, did'nt see anything in the archive: map('world',pro='rectangular',para=0) yields a strange artifact (horizontal bar) extending over the whole map at a certain latitude range (approx 65 deg. north), whereas map('world',pro='rectangular',para=180) (which should be the same) does not show the artifact. the artifact shows up in other projections as well,

Apologies in advance for the question. I am trying to draw a map of the US as a surface plot so that I would be able to drop bars on the different states (something like Uwe Ligges' scatterplot3d example 4). I am not sure where to start looking for such a beast. If anyone has any pointers, ideas, I will be grateful. TIA, Partha

Hi, Does anyone know of a method for writing text to the graphics window, where there is *no* plot? Basically, I have developed a 'significance test' and I would like the output on the graphics window to say something about the input parameters and the stats of the significance test. Any help would be appreciated. Cheers, Sam.
