Hi, Can someone help me with the following? I currently have the following plot:
plot(c(0,14,0,14),c(0,5,0,5),ann = FALSE, xaxs="i", yaxs="i",bty="L" )
polygon(c(0,18,18), c(0,6,0), col='light grey', border = NA)
polygon(c(0,18,18), c(0,2,0), col='grey', border = NA) However, I would like to
make such a plot, but where there is a continuous shading changing fom white to
darkgrey. Can anyone give me any suggsetions how to do this in R? Thank you,
Elisabeth

Hi Elisabeth,
For a quick hack, try this:
segments(rep(0,100),seq(-4.5,0,length.out=200),rep(14,200),
seq(0,4.5,length.out=200),
col=rgb(seq(0.8,0.5,length.out=200),seq(0.8,0.5,length.out=200),
seq(0.8,0.5,length.out=200)),lwd=2)
Jim
