 > How can I read and plot an ArcGIS raster file into R ?

Hi Juliane,

I think what you are looking for is something like a function in the 
"adehabitat" package called "import.asc". First you need to convert your 
raster images in ArcGIS to ascii files. You have to use the conversion 
toolbox --> from raster to --> raster to ascii in ArcGIS.

see also:

afterwards apply the image.asc function.

this might help you out:

this allows to import your raster files and use it for calculations.
are you sure about your floating point data? or are there only "some" 
digits after the "." ?

hope this helped?
