Re: [R] ggplot2 will not draw a rectangle. Error: ggplot2 doesn't know how to deal with data of class XXX
Thanks to everyone on this. Both Jeff's and Rui's approach worked. It looks like they do equivalent things , that is supplying the x and y values in geom_rect. The worst of it is I think I saw an example using the NULL NULL approach and did not realise the significance of it.

What is really annoying is that I can find examples on the web that work just fine and I cannot se how my example is that different. I even tried changing from using as.Date() to POSIXct() and to POSIXlt in case the dates were the problem but with no luck. I think it's time for dinner here so I will have another look at it tommorrow --hopefully someone will see the problem. Thanks again.

Re: [R] ggplot2 will not draw a rectangle. Error: ggplot2 doesn't know how to deal with data of class XXX
Hello, You're forgeting to tell gfeom_rect that the x and y aesthetics are already set elsewhere. You must include NULL, NULL as the first two arguments: p + geom_rect(data = rectlib, aes(NULL, NULL, xmin = xmin, xmax = xmax, ymin = -Inf, ymax = Inf), fill='red', alpha=0.2) Hope this helps, Rui Barradas Em 22-03-2013 21:01, John Kane escreveu: Ah , thanks Sarah So that's why the error message changed!
