[R] Removing cell borders from svg or eps in levelplot

[Pascal Oettli]

Hello,

Please try including "panel=panel.levelplot.raster" as an option of "levelplot":

> svg("SVG.svg")
> levelplot(prt, main="SVG", xlab=NULL, ylab=NULL, col.regions=rgb.palette(800), cuts=100, at=seq(0,1.0,0.01), panel=panel.levelplot.raster)
> dev.off()

It may help you.

Regards,
Pascal
