Dear all,
Happy new year!
I posted a very similar question a few days ago, but probably too
cluttered. Here is a tidy, minimal version:
I want to make a package, with a data.frame d and a function f given
below. Now, the function f needs to use the data.frame d. I could
(and that's what I've done temporarily) make a local duplicate of
this data.frame in the function definition, but it seems silly.
I've tried "attach()", "data()", but both fail when running R CMD
check with the error
> * checking R code for possible problems ... NOTE
> f: no visible binding for global variable 'd'
Here is the minimal package skeleton:
> d <- data.frame(a=1)
>
> f <- function(x)
> {
> data("d")
> x+d$a
> }
>
> package.skeleton(list=c("f","d"), name="mypkg")
What would be a sensible way to refer to this data inside the package?
Best regards,
baptiste
