Using rworldmap package requires loading library(methods). I am writing it here because it was really not obvious.
R could not find function "checkAtAssignment" while running rworldmap
Frage
I need your help with R not being able to run a function with rworldmap package.
When using rworldmap package in R and trying to 'joinCountryData2Map'
sPDF <- joinCountryData2Map (myframe, joinCode = "NAME", nameJoinColumn = "location", verbose = TRUE, suggestForFailedCodes = TRUE )
I get the following error:
Error in mapWithData@data <- cbind(mapWithData@data, dF[matchPosnsInUserData, :
could not find function "checkAtAssignment"
Calls: joinCountryData2Map
Execution halted
My guess is that R needs methods package, which I could not find for my R version.
Any suggestings why I 'could not find function "checkAtAssignment"'?
My R version is 3.0.2 Patched.
Lösung

Dunno what "R 3.0.2 Patched" means, but yes you are correct that somehow you don't have the methods
package, which is included in the standard installation package. How about reinstalling R
from the binaries or source tarball at CRAN -- that should solve your problem.
