Hi group,
Please help me print a legend for a plot printed with this command:

ggmap(hdf,extent = 'device', legend = 'none') + geom_point(
    data = resn,aes(x = ln, y = lt,color=b))

where b is a column with numbers 1,2,3 to differ the colors of points from
each other.

Legend should have a title and show a description for each color.
Also if possible show me how to customize the colors and not let the plot
chose them.


Thx
