9 years ago I'm off this coming week so won't have a chance to look at it in detail for a bit, but will try to do so soon after I get back.
To clarify: if you ignore the plotting of the state boundaries, can you get Shiny to work just in terms of plotting the raster images of the composition estimates on a simple x-y grid - the Albers x-y we are using? I.e. if you use my ggplot2 code w/o the add_map_albers part, does it work?
I'm a bit confused as to what you are trying to do - why are you trying to first plot the shapeFile and then use make_veg_map? Does it not work to simply read in and create usFortified and pass that to make_veg_map, which calls add_map_albers to overlay the state boundaries? Without delving deeply, it would appear to me that initial plotting of the shapeFile in server.R would use base R graphics and not ggplot2 and then make_veg_map would come along and wipe out the initial plot and create a ggplot2 plot.

The main issue I need help with is visualizing the maps. I can create the maps using the maps.R file and we have the ui.R file that controls how the webpage looks. But we can't get the server.R file to work. You'll see some code at the top regarding a Canada shapefile. Alex Dye sent code he had been working on for a Shiny App course, so we played around with that. Then we also have code at the bottom where we tried to plug in the code from maps.R. But we were not able to get the US albers shapefile to visualize and therefore was unable to visualize the maps.
I haven't had time to look at the leaflet package Simon mentioned on our phone call, but will do so soon.
