[R-pkg-devel] Confusing error

Hello,

I am trying to submit an R package to CRAN. There are no notes, comments or errors when checking on my local machine, but I keep getting an error message when submitting. I am attaching the log file, but basically the error occurs when running the examples. In particular, it says

Error in loadNamespace(x) : there is no package called 'survey'

However, my package does not use the ?survey? package, and when I include this package to the Imports field in the DESCRIPTION file, it gives the following NOTE:

checking dependencies in R code ... NOTE
  Namespace in Imports field not imported from: ?survey?
    All declared Imports should be used.


How do I resolve this issue?

Best,
Aaron

Hello, thank you for getting back to me. I have a github with the code:

https://github.com/237triangle/surveynnet

The main code is in R/surveynnet.R.

Re: your suggestion, do you mean I should de-install the survey package? I will try that, but would appreciate any additional help in the meantime so I?m linking my github above.

Best,
Aaron

My guess is that one of your packages uses survey as a Suggested package.
And your calling a function from that package that uses survey via
Suggests.

Is your package on GitHub? Or could you share your Imports?

The PracTools::deffCR function calls survey::svydesign.  It only 
suggests the survey package, so it is not necessarily available.

What you could do is also suggest survey, then add a test for its 
presence before calling PracTools::deffCR.  Or if that call is 
essential, then you should import survey, and add some innocuous direct 
reference to it to quiet the NOTE.

Thank you [and Josiah Parry] for your help; I had already seen that PracTools uses `survey` but only suggests it, and I was unsure what to do on my end since I was getting in trouble whether I imported it or not. I will try doing what you suggest.

Since the call to PracTools::deffCR is essential to this package, I will do the second suggestion.

Best,
Aaron

Since you have dplyr as a dependency (though I?d reconsider that one since
it can be quite hefty / change it?s API) I would suggest using
rlang::check_installer(?survey?) in the function that indirectly calls
survey.

This will throw an informative error when survey is not found.

In your examples you can wrap your example like:

if (rlang::is_installed(?survey?)) {

}
