Does anyone know of a package to make a map from GIS data, and/or would it be easier in one of the free GIS programs. I would like to make a map of the savannah river area with our sampling locations. thanks stephen -- Let's not spend our time and resources thinking about things that are so little or so large that all they really do for us is puff us up and make us feel like gods.

There are many ways to do this, depending on what type of spatial data you are working with and what you want your maps to look like. The sp package provides S4 classes and methods for working with GIS data. Two likely candidates for importing data are the rgdal and maptools packages. See the Spatial Task View: http://cran.r-project.org/web/packages/rgdal/index.html Also, there is a r-sig for spatial data: https://stat.ethz.ch/mailman/listinfo/r-sig-geo Kingsford Jones On Thu, May 1, 2008 at 6:56 AM, stephen sefick <ssefick at gmail.com> wrote:> Does anyone know of a package to make a map from GIS data, and/or would it > be easier in one of the free GIS programs.

Hi, Is actually not a question for myself but for my sister. See uses Matlab for her study movement sciences. See likes to try free software, what is a good alternative for matlab? Regards, Dirk
