> 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: http://webhelp.esri.com/arcgisdesktop/9.2/index.cfm?TopicName=Raster_to_ASCII_(Conversion) afterwards apply the image.asc function. this might help you out: http://finzi.psych.upenn.edu/R/library/adehabitat/html/import.asc.html 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? best, Jens -- > -------------------------------------------------------- > Jens Oldeland > Universität Hamburg > Biozentrum Klein Flottbek > Ohnhorststr. 18 > 22605 Hamburg > > Tel.: +0049-(0)40-42816-407 > Fax: +0049-(0)40-42816-539 > > Email: [EMAIL PROTECTED] > Email: [EMAIL PROTECTED] > Web: http://www.biologie.uni-hamburg.de/bzf/fbda005/fbda005_e.htm > -------------------------------------------------------- ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
