no internet connection

[xtimbeau]

Apparently when no internet connection available and even is the jar for R5 is cached, setup_r5 fails. Looks like issue #163.

to be more specific, it is when the connection attempt is timing out. Apparently there is no error returned in that case and r5r assumes the connection is live, but fails to download metadata

Hi @xtimbeau. Thanks for opening this issue. According to CRAN policies, the function should "fail gracefully" by simply returning a message when there is no internet connection. This should be done with the check_connection() support function in r5r, but apparently this is not working as expected.I'll look into this, but it might take a couple weeks for me to solve this issue due to other commitments.

If you know already how to address this problem, please go ahead and submit a pull request.

hi, the problem occurs when the download_metadata() is timing out. The reason why is unclear to me, but it is not an issue with internet. I was using r5r on an azure machine in europe and support suggested to me it was linked to connection with brazil. Whatever, a turnaround would be to add an option to skip the donwload_metadata part and behave like there was no internet connection. Thus it would use the donwloaded jar directly.

As per 9c0ed76 r5r doesn't require internet to fetch the metadata anymore. Instead, it always uses the metadata stored inside extdata.

Also, b9193cf ensures that check_connection() is used properly, "failing gracefully" when either the user doesn't have internet access or the IPEA's server is not responding.

These commits, when coupled, reduces r5r's internet dependency quite considerably. Internet is now only required to download the latest R5 jar if it hasn't been downloaded before.

Thanks, Daniel. Could you please document this in the NEWS file?

Done.
