Hi, 

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) 

Ugh, sorry I meant to try this: 

plot(raster(volcano), useRaster = FALSE) 

otherwise both calls are equivalent. 

Cheers, Mike. 

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
