The conventions for R graphics devices changed in R 2.0.0, in particular the way the alpha channel is represented. I doubt if the same version of a graphics device works in both R < 2.0.0 and R >= 2.0.0, and this one appears to predate R 2.0.0.

Dear list members,
I have a probably simple question concerning the RSvgDevice. After upgrading from R 1.9.0 to R 2.0.1 the computet svg files looking empty. Each time the RSvgDevice 0.5.3 were used.
Scales and headers are printed but the plots are missing: <rect x="433.10" y="246.13" width="0.93" height="29.74" style="stroke-width:1;stroke:none;fill:none"/> <rect x="434.02" y="201.52" width="0.93" height="74.35" style="stroke-width:1;stroke:none;fill:none"/> <rect x="434.95" y="201.52" width="0.93" height="74.35" style="stroke-width:1;stroke:none;fill:none"/>
before updating the svg looked like that: <rect x="431.61" y="251.09" width="1.12" height="24.78" style="stroke-width:1;stroke:#000000;fill:#32CD32" /> <rect x="432.72" y="261.00" width="1.12" height="14.87" style="stroke-width:1;stroke:#000000;fill:#32CD32" /> <rect x="433.84" y="256.04" width="1.12" height="19.83" style="stroke-width:1;stroke:#000000;fill:#32CD32" />
So it seems to be the "stroke:none;fill:none" text which will let the plot be "invisible"?
I use following code: devSVG( file=filename, height = plot_height, width = plot_width, xmlHeader=TRUE, onefile=TRUE) plot1<-barplot(MI, col=c('limegreen'), beside=TRUE, width = c(1,1), space = c(0,1), ylab='mutual inf.', ylim=c(0,1), main=headertext) ... dev.off()
I definitly changed no code, but the plot is invisible.
Any help would be appreciated!
Thanks for any help.
Jan
