dear R users,
I would like to fill a circle with yellow stripes instead of a uniform
yellow color. To draw the circle I used the following command after
having loaded the (very nice !) plotrix library :
library(plotrix)
pdf("MWE.pdf",width=8, height=8)
plot(seq(-12.5,-8.7,length.out=100),seq(-11.3,-8.3,length.out=100),type="l",col="red",xlim=c(-12.5,-8.7),ylim=c(-11.5,-8.5))
par(new=T)
plot(seq(-12.5,-8.7,length.out=100),seq(-11.7,-8.7,length.out=100),type="l",col="red",xlim=c(-12.5,-8.7),ylim=c(-11.5,-8.5))
par(new=T)
polygon(c(seq(-12.5,-8.7,length.out=100),
rev(seq(-12.5,-8.7,length.out=100))), c(seq(-11.3,-8.3,length.out=100),
rev(seq(-11.7,-8.7,length.out=100))),
col = alpha("red",0.4), border = NA)
par(new=T)
draw.circle(-12.85,-10.9,0.85,nv=1000,border=NULL,col="yellow",lty=1,lwd=1)
dev.off()
It looks a bit ugly since they are not real data, but it is the simplest
MWE example that I found.
Thanks, best
Jean-Philippe

I don't see a question. If your question is whether R supports pattern fills, AFAIK it does not. If that is not your question, ask one. -- Sent from my phone. Please excuse my brevity.

The `polygon` function has 'density' and 'angle' argument that with 'col' and 'lwd' can make slanted fill lines. This is a modification of hte first example on `?polygon`? x <- c(1:9, 8:1) y <- c(1, 2*(5:3), 2, -1, 17, 9, 8, 2:9) op <- par(mfcol = c(3, 1)) for(xpd in c(FALSE, TRUE, NA)) { plot(1:10, main = paste("xpd =", xpd)) box("figure", col = "pink", lwd = 3) polygon(x, y, xpd = xpd, col = "orange", density=3, angle=45, lwd = 5, border = "red") } The polygon function is _not_ in pkg::plotrix.>> It looks a bit ugly since they are not real data, but it is the >> simplest >> MWE example that I found. >> >> >> Thanks, best >> >> >> Jean-Philippe > > ______________________________________________ > R-help at r-project.org mailing list -- To UNSUBSCRIBE and more, see > 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.David Winsemius Alameda, CA, USA
