ggplot.Predict uneven legend colors on multiplot about rms

[harrelfe]

I fixed show_guide but the color problem persists. I typed ggplot(p, group='.set.') to show the ggplot2 expression that ggplot.Predict is using:

[1] "ggplot(zz, aes(x=.xx., y=.yhat, color=.cond)) + geom_line() + coord_cartesian(ylim=c(2, 12)) + labs(x=expression(x1), y=\"y1\") + theme(plot.margin = grid::unit(rep(0, 4), 'cm')) + colFun(name=expression(Set)) + theme(legend.position='top') + tanova(w, xa, ya, c(2, 8), c(2, 12), flip=FALSE) + geom_ribbon(aes(ymin=lower, ymax=upper), alpha=0.2, linetype=0, fill=I('black'),show.legend=FALSE)"

If you can see what's wrong with my ggplot2 calls I can fix.

I'm also using the ggplot.Predict function. I was wondering whether I can change the background theme as white. It seems that I cannot directly use "+ theme_bw()".

Try using the addlayer argument
