plotting rasters - no plot, no error

Hi, I have the current version of R installed on 2 different Windows computers. On one i can plot using the plot function a raster in geotif format, on the other it plots only the axis, an empty color bar and no raster what so ever without generating any errors or warnings. So i suspect something is not installed properly, but i don't know what. Do you have any clues? I would really appreciate any insights. I need some instructions i can pass on to an IT person since i don't have rights on the computer that does not plot the raster.
Hello, can you try these on both systems and see if there's a difference? library(raster) plot(raster(volcano)) plot(raster(volcano), useRaster = TRUE) the useRaster argument refers to use of graphics::rasterImage rather than image.defaul under (package) raster's hood. Cheers, Mike.
On both computers i can plot lines, points, polygons, as graphic objects
or shapefiles.
Thanks so much, Monica
