Hi Mo.
Perhaps smartlegend in gplots may be what you are looking for. The
example below might _not_ be close to what you demonstrate above - it's
just an example.
# install gplots if not installed
library(gplots)
# plot a density
plot(density(mod.b2.06, from=0, to=6000), main="Density plots for both
the pre- & postfire MODIS bands 2, 6 and 7", col="magenta", lty=2,
lwd=2)
# add another one
lines(density(mod.b2.07, from=0, to=6000), col="magenta4", lty=1, lwd=2)
# example of smartlegend
smartlegend(x="right", y="top", c("Prefire MODIS band 2", "Postfire
MODIS band 2"), col=c("magenta", "magenta4"), lty=2:1, lwd=2, cex=1.5)
Hope this helps.
Kindest regards, Nikos
