[R] Different type of legend?

[Kevin Burton]

Sorry this is the commands I am using:

                colors <- grey(0:10/10)");

                leg.txt <- c("-1", "0", "1")
                mo <- map('county', projection='polyconic')");
 
color.legend(mo$range[1]-1,mo$range[2]+1,mo$range[3]-3,mo$range[3]-1," +
 
"leg.txt[c(1,length(leg.txt)/2,length(leg.txt))],colors[-1],align='rb',col=c
olors[-1][c(1,length(colors[-1])/2,length(colors[-1]))])");

Hi Kevin,
The color.legend function (plotrix) might do what you want.
