ne_download() not working properly #11

Closed Mavromatika closed 8 years ago

Mavromatika commented 8 years ago

Hi, I discovered this package in Hadley Wickham's book, and I think it's very useful. I've been playing with it a bit since yesterday, and it turns out that ne_download() can't download everything that's listed in the help page. I have tried airports, ports, railroads and they won't work (I get a 404 or a timeout error). The command I used is : ne_download(category="cultural", type="airports")

It works fine for populated places though. Any idea why ?

Thankyou for the useful feedback.

The issue is because Natural Earth data aren't available for those at the default scale of 110. Changing to this should work for you : ne_download(category="cultural", type="airports",scale=50) ne_download(category="cultural", type="airports",scale="medium")

?ne_download shows a table of data availability at the different scales, but I'll try to add a warning if you try one that's not available.

Thank you for your answer. I confirm that it works. Editing the help file would be good indeed, as the error one gets isn't very informative.

Thanks @Mavromatika. I've added a check and warning message. Can you check this works for you ? If so I'll then close the issue. Andy

Is this the message ? In check_data_exist(scale = scale, category = category, type = type) : your combination of type, category, scale seem not to exist in the list of Natural Earth data so you may get a download fail message. Check ?ne_download or http://www.naturalearthdata.com/features/ to see data availability.

Yes. Do you find that helpful? Would you suggest anything else?

No, I think that should do. Thank you very much for your help !
