Help with map
I have just learned how to play with map, but something weird (or not) is happening. Suppose I want to draw a map of two countries (that have disconnected components), like Argentina and Brazil. If I command: library(maps) library(mapdata) map("worldHires", c("Argentina", "Brazil")) It works fine. However, if I want to _colour_ the interior:

SpatialPolygonsDataFrame to map conversion?
Dear list, I'd like to use the function smooth.map{maps} to smooth out aggregated spatial data. The first argument to this function must be a map object. I have a shape file which I read with readShapeSpatial{maptools} and I got an object of class "SpatialPolygonsDataFrame". Is it possible to create a map object from a SpatialPolygonsDataFrame object? Alternatively, is there any

KVM does not start anymore
Hi, I had a C7 virtual machine running on a C7 host for several weeks without any problems. Today I rebootet the host and now the virtual machine does not start anymore. I can see grub coming up and starting the kernel. After some seconds the last thing that is visble on the VM console is "ss perfctr msr (MSR c1 is0)" then the screen goes blank with just a blinking cursor in the upper

plot methods in sp
Dear listers, I am working since a while with the sp package and still wonder how the plot methods are managed with sp spatial objects. For instance, SpatialPolygonsDataFrame objects have obviously a plot method. However it cannot be found in the list provided by methods(plot) . Furthermore ?plot.SpatialPolygonsDataFrame, nor ?plot.SpatialPolygons, etc.. provide a help, though the lattice

Dissolve polygon
Hi, I am working with a SpatialPolygonsDataFrame of many islands. There are a lot of polygons (islands) composing my SpatialPolygonsDataFrame. I want to extract the elevation of each island. I need to separate the different polygons (like dissolve function in arcgis), to have the elevation of each island. Do you have any idea how can I do that ? I already read a lot of forum, and read the

extract data from shapefiles
I'm hoping that someone could guide me in how to extract data from shapefiles. I want to extract data from a shapefile (classed as "SpatialPolygonsDataFrame") and more specifically, the data is contained within the slot called "coords" from the class "polygons" within this file and despite my best efforts (and much reading!), I'm at a lost.
