Re: [R] maptools: using to sets of information (within two shape files) for one plot
Hello Mike, thank you very much for the information about the projections and the R-Sig-Geo mailinglist! For now I solved the problem by getting another shape file with the same projections so I didn't have to reproject the data sets. However, I might need this in the future - if so your information will be of good use to me. Thanks again! Marion 2012/5/31 Michael Sumner mdsum...@gmail.com 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.
