I want to save my raster plot that produced with R to ArcGIS raster (.img, .tif and ASCII) file.
Have a look at
?writeRaster from the
raster package. Depending on the desired output format, just edit the format argument ("GTiff" for .tif, "HFA" for .img, and "ascii" for ESRI .asc). Here's some sample code,
writeRaster(yourRasterObject, "outputFilename", format = "GTiff")
