[R] maptools: using to sets of information (within two shape files) for one plot
Dear all, I am using a shape file containing the information regarding the borders of the PARISHES of Austria. I created a plot with different colours for different percentages of child care institutions. Now I would like to add the information of the COUNTY boundaries to this plot which I have got in another shape file. I would like these boundaries to be shown with bold lines so that they can be seen well. I tried this with adding another plot to the existing plot, but the second plot was not at the same place as the first plot and I couldn't change that by using the commands fig or mar. Could anybody help me with this? Thank you very much in advance. Marion [[alternative HTML version deleted]]

Please let us know at least what package/s you are using to read the data from shapefiles and the code you are using. The two data sets may be using different projections, so use summary(obj1) and summary(obj2) to describe their projection metadata and data extents (well, at least if they are Spatial* objects from the sp package). With sp/rgdal, or other packages these can be reprojected if you know the original coordinate systems so that plotting them together makes sense. There are good resources and vignettes sp and related tools that explain this, and a dedicated mailing list for data like these (R-Sig-Geo). Cheers, Mike.
