figuring out state key names, or other problem

mapping.R

test <- data.frame(state=c("Florida", "Virginia", "Texas", "California",
                           "Georgia", "North Carolina", "New York",
                           "Missouri", "Illinois", "Maryland", "Pennsylvania",
                           "Tennessee", "Colorado", "Washington", "Arizona",
                           "Ohio", "Wisconsin", "District of Columbia",
                           "Michigan", "New Jersey", "Utah", "Louisiana",
                           "Minnesota", "Alabama", "Kansas", "Massachusetts",
                           "Indiana", "South Carolina", "Arkansas", "Oregon",
                           "Nevada", "Kentucky", "Nebraska", "(not set)",
                           "Connecticut", "New Mexico", "Oklahoma",
                           "West Virginia", "Iowa", "Hawaii", "Rhode Island",
                           "Mississippi", "Maine", "New Hampshire", "Delaware",
                           "Alaska", "Idaho", "North Dakota", "Vermont",
                           "Montana", "South Dakota", "Wyoming"),
                   value1=rnorm(52),
                   value2=rnorm(52))

library(rMaps)
crosslet(x="state",
         y=c("value1", "value2"),
         data=test,
         map="us")

The default maps use abbreviated state names as keys. So just do

test = transform(test, state_abb = state.abb[match(state, state.name)])
crosslet(
  x = "state_abb",
  y = c("value1", "value2"),
  data = test,
   map = "us"
)

@ramnathv Thanks, that should get this closer to working - but it still isn't working. :(

Ah! Looking at the HTML that gets generated, it looks like it's trying to pull in topo json for US counties - I don't think that even has the states in it by themselves! Right? Do I just need to find topo json for the states?

Yes. You do need topojson for US states. Let me know if you are able to get it working or hit another bottleneck.
