R help - Feb 2014 - Removing cell borders from svg or eps in levelplot

Hi,

I am using function svg to save a lattice::levelplot, and ending up in some kind
of line or border around each cells of the plot. However, if I save the plot in
png, I dont get the border. But I need the plot to be saved in svg or pdf. In
both svg and pdf I get the same result.

I am saving in the following way:

library(lattice)
rgb.palette <- colorRampPalette(c("black", "yellow",
"red"), space = "rgb")

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) )
dev.off()

png("PNG.png")
levelplot(prt, main="PNG", xlab=NULL, ylab=NULL,
col.regions=rgb.palette(800), cuts=100, at=seq(0,1.0,0.01) )
dev.off()

Is there a way to get rid of these lines from the plot in svg. I went through
the thread "Remove "gray grid" from levelplot"
[https://stat.ethz.ch/pipermail/r-help/2006-March/100683.html], but that didnt
help me much.
I am attaching a screenshot to show the difference.

Please advice me if I am wrong some where, or if there is a way to get rid of
these borders.

Thanks.

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
