What am I missing? When I run the code below I get the error message
"Error: ggplot2 doesn't know how to deal with data of class function"
Googling suggests a message of "Error: ggplot2 doesn't know how to deal with data of class XXX" is not uncommon but I don't see why I am getting a "function" error unless I am using some reserved word?

ggplot2 will not draw a rectangle. Error: ggplot2 doesn't know how to deal with data of class XXX"
8 messages · Sarah Goslee, John Kane, Rui Barradas +1 more
Hi John, This bit of your code: geom_rect(data=rect Your reproducible example doesn't create rect, and rect() already exists, so geom_rect() is trying to treat a function as data. Sarah

Ah , thanks Sarah
So that's why the error message changed! I was getting different one earlier.
I had defined rect earlier and apparently, when stripping down the code I negelected to include it in the example. Renamed rect as rectlib
Now what I get is "Error in eval(expr, envir, enclos) : object 'federal.ps' not found" which is what I was getting ealier although at one point I was getting "year not found".
See revised code.

Thanks, that shows that I am not making one of my "really stupid" mistakes. 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. John Kane Kingston ON Canada

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:

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. John Kane Kingston ON Canada
