import of data set and warning from R CMD check
Dear Thierry, Thanks, that indeed solved the warning. Still, I think the message from R CMD check is confusing since the hint seems not to work with the current R version. Pascal

Dear Pascal,
You could try to use data(CO2, package = "datasets") instead of data(CO2)

To call in the statistician after the experiment is done may be no more
than asking him to perform a post-mortem examination: he may be able to
say what the experiment died of. ~ Sir Ronald Aylmer Fisher
The plural of anecdote is not data. ~ Roger Brinner
The combination of some data and an aching desire for an answer does not
ensure that a reasonable answer can be extracted from a given body of
data. ~ John Tukey

Hi all,
When checking an R package, I get:
|Consider adding importFrom("datasets","CO2")
(this data set is used in some example code)
However, when I add the suggested 'importFrom' statement to NAMESPACE
(using roxygen2), I get
|
|Error :object ?CO2? is not exported by 'namespace:datasets'|
||
|I understand that datasets are not exported, and the comment printed by
'R CMD check' seems not to have any consequences, but it nevertheless
seems inconsistent to me. But maybe I miss something here...
