You could use the mar= argument of the par() function to define a wider
plot margin on the right, then change the first and third arguments of
color.legend() to make the legend fit in the margin. For example,
par(mar=c(3, 1, 3, 7))
color2D.matplot(test, axes="F", xlab="", ylab="", main="color.scale",
extremes=c("#FF0000","#FFFF00"), show.legend=FALSE)
axis(1, at=seq(1, ncol(test), length.out=10), labels=seq(201, 300,
length.out=10))
color.legend(105, 30, 115, 70, seq(-110, -30, length=11), align="rb",
rect.col=color.scale(1:30, 1, c(0,1), 0), gradient="y")
