Re: [R] Transparent Labels for Polar Plot

Hi Jimmy, The easiest way is to change the following lines near the bottom of the radial.plot function: boxed.labels(grid.pos-radial.lim[1],ypos,radial.labels,border=FALSE, cex=par(cex.lab)) to text(grid.pos-radial.lim[1],ypos,radial.labels,cex=par(cex.lab)) If this is a Good Idea, I'll add an option to do one or the other.

[R] Transparent Labels for Polar Plot
Hello, I am currently using the polar.plot function in the plotrix package to graph data. Unfortunately, it seems that the default for the labels is to have a background color that is covering the line representing my data, making it difficult to read. Is there a way to make this label background transparent? Example: lengths - 0:72 bearing - seq(from=0, to=360, by=5) polar.plot(lengths, bearing, labels = seq(from=0, to=340, by=20),label.pos = seq(from=0, to=340, by=20), start=90, clockwise=TRUE, rp.type=p, line.col=aquamarine3, lwd=2, main=Title, radial.lim=seq(from=0, to=90, by=15)) ##label at length 20 blocks view of the line around bearing 100 Thanks for your help! -Jimmy __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
