OK, thanks for the tip on good coding practice. I'm still getting the NOTE though when I make the suggested change.
Because when you do return(RutgersMapB36[,1]), the code checker has no
way to know that the RutgersMapB36 variable is actually defined.
Try this:
test<-function() {
RutgersMapB36<- NULL
data(RutgersMapB36)
return(RutgersMapB36[,1])
}
That might remove the NOTE, but as far as I can see, it also breaks the code...
oops, right...
This should remove the NOTE and work (hopefully):
test<-function() {
data("RutgersMapB36") # loads RutgersMapB36 in .GlobalEnv
RutgersMapB36 <- get("RutgersMapB36", envir=.GlobalEnv)
return(RutgersMapB36[,1])
}
Cheers,
