Is it possible to place maps onto lattice plots?
With basic plotting you can add a map to a plot
library(lattice)
long<-c(-69.2, -69.5, -70.1, -70.3)
lat<-c(41, 41.5, 43.2, 42.8)
plot(long, lat)
map('state', c("massachusetts"),add=TRUE)
but is it possible with lattice?
library(lattice)
factor<-c(1,1,2,2)
xyplot(lat~long|fact)
...now what?
I have looked at panel and found through google an extravagant shape
file export/import to R.
Is there a simpler fix?
Thank you very much for your help.
