Hi all,
What should you do when you rely on a data only package. If you just
"Depend" on it, you get the following from R CMD check:
Package in Depends field not imported from: 'hflights'
These packages needs to imported from for the case when
this namespace is loaded but not attached.
But there's nothing in the namespace to import, so adding it to
imports doesn't seem like the right answer. Is that just a spurious
note?

I don't know whether the author of that note would consider it spurious
or not. A simple workaround for you (as the author of hflights) is to
put a function into the namespace. For example, get_hflights(), that
gets a copy of the data:
get_hflights <- function() {
data("hflights", package="hflights", envir=environment())
hflights
}
I don't know a simple workaround for someone who depends on a data-only
package that they did not author.
