[R-sig-Geo] Saving plot as PDF from functions levelplot and gplot from rasterVis package

[baptiste auguie]

Hi,

Have you tried geom_raster and panel.levelplot.raster respectively, if
your image has regular tiles? "grid lines" artefacts are often
reported as a bug from pdf viewers when the image is made of multiple
rectGrobs.

HTH,

baptiste
