Hello,
See if this is it. The standard trick is to reshape the data from wide
to long, see the SO post [1]. Then add a scale_shape_* layer to the plot.
yyy <- cbind(xxx, y3 = y3)
long <- reshape2::melt(yyy, id.vars = c("x", "y1", "grp"))
ggplot(long, aes(x, y = value, colour = variable, shape = variable)) +
geom_line(aes(y = y1)) +
geom_point() +
scale_colour_manual("Doesn't work",values=c("blue","red"),
labels=c("clyde","irving")) +
scale_shape_manual("Doesn't work",values=c(16,3),
labels=c("clyde","irving")) +
facet_grid(cols=vars(grp))

Hope this helps,
Almost there. However the colour of the line changes with "values" and
lines show up in the legend. I want the lines to be black in all
facets, and only points to show up in the legend.
I fiddled about a bit trying to achieve this but only succeeded in
messing things up completely.
Can you guide me a bit further, please?
cheers,
Rolf
