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
