Hello,
Or with base R only,
smooth <- colorRampPalette(c('white', 'darkgrey'))
segments(rep(0,100),seq(-4.5,0,length.out=200),rep(14,200),
seq(0,4.5,length.out=200), col = smooth(200), lwd = 2)
Hope this helps,
Rui Barradas

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)
and even easier:
library(plotrix)
segments(rep(0,100),seq(-4.5,0,length.out=200),rep(14,200),
seq(0,4.5,length.out=200),col=smoothColors("white",198,"darkgray"))
