Hi:
Does anybody know if there is a workaround about the legend diagonal
lines or points?
I found this old thread and thought it could be something inside opts
to take care of this and make it optional

Hi Felipe, I think you just add legend = FALSE to the geom call.

Thanks Luciano but I did try that before I posted. My legend colors
turn white after I
use legend=TRUE but nothing happens to the labels. I'll try a couple
more things.

Felipe, the code in the other post you sent describes your issue. I don't know how to do it but I have an ugly workaround. I added geom_polygon without color="blue", which will make a nice legend, and plot on top of it the geom with blue borders.

utah_basins <- ggplot(shp2,aes(long,lat,group=group,fill=level3_nam)) +

geom_polygon() + geom_polygon(colour="blue", legend = F)

utah_basins

Thanks Luciano:

I've done things like that where I had to call geom_point() or geom_line to make work but

I didn't even think about doing this with geom_polygon(). Is a great workaround but I don't understand

why it wouldn't work with just one geom. Thanks again and the shapefile was the example I was

talking about. Now I am trying to figure out why one of my shapes with the same name is not being filled.

This is Hadley's design choice. He wants the legend to be match exactly the geom. Maybe, this can be confusing as the blue outlines does not change over the levels. Hadley, would be too hard to have an option to turn this behaviour off?
