Hello, I am using RArcInfo to create some maps but, once I have plotted the map (using plotarc), I try to add new lines, but the fact is that they are not plotted. I have reviewing the code, and if I remove a line, everything works fine, but I am not sure whether I should do that, because that line restores the previous 'par' profile. Here is a portion of the code (from plotarc.R):...

I am having trouble using get.bnddata() in the RArcInfo package. I installed the version 0.2 binary of the package for Windows and am using R 1.4.1 on Windows NT 4.0. I have had no problems importing and plotting arc data with get.arcdata() and plotarc(). plotpal() also works fine. I've been able to use get.arcdata(), get.labdata(), get.paldata(), get.tablenames(), get.tablefields(), get.tabledata(). When I try get.bnddata() as follows, I get an error: > wet.bnd <- get.bnddata("wetlands\\info", "WETLANDS.BND") E...

i am using the rarcinfo package to draw maps. for maps, th aspect ratio is quite important. how can i control the aspect ratio and the size of a graphics window in the mswindows version of R and more generally in R in general. i would like to e able to both set the size before or while the window is corrected, and also for a window which already exists. -- -- Erich Neuwirth, Computer Supported
