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])
}
Cheers,
H.
In case it matters, I'm check'ing with
R version 2.15.0 (2012-03-30)
Platform: i386-pc-mingw32/i386 (32-bit)

I'm developing a package that comes with a data set called
RutgersMapB36. One of the package's functions requires this data
frame. A toy example is:
test<-function() {
data(RutgersMapB36)
return(RutgersMapB36[,1])
}
R CMD check returns a NOTE:
test: no visible binding for global variable 'RutgersMapB36'
Is there any way to avoid this NOTE?
Use data("RutgersMapB36"), which many think is good practice in code.
Thanks,
Brad
