Unfortunately I am still getting the same error: install.packages(c("choroplethr", "acs")) library(acs) api.key.install("f8b2a6df01479981aef39577b3c4466f5a4c8274") detach("package:acs", unload=TRUE)
library(choroplethr) get_state_demographics() Error in (function (classes, fdef, mtable) : unable to find an inherited method for function ‘geography’ for signature ‘"matrix"’ Someone suggested that I import the acs class in my NAMESPACE. But even after adding: importClassesFrom(acs,acs) I get the same error.
