No internet connection with R Studio to download wdpa data?

[ankemueller]

Dear Jeff, I was excited to try out your wdpar package and downloaded it yesterday. When I tried to let your example run I received the following error:

mlt_raw_pa_data <- wdpa_fetch("MLT", wait = TRUE)

Error in wdpa_fetch("MLT", wait = TRUE) : data not found in download_dir, and no internet connectionto download it.

As far as I understood your description, WDPA data should be downloaded by your package automatically, so no need for me to manually put something in the download-dir, right? I do not understand why I get the "no internet connection" error as I am connected to the internet and downloading packages from CRAN works just fine. I use R Studio Version 1.1.463 and R Version 3.5.2. Maybe you have an idea why it is not working for me?

Anyway, thanks for providing this cool package! Cheers, Anke

Hi,

Yeah, you should be able to download the data automatically with wdpa_fetch. This package uses the pingr::is_online function to detect if you have an internet connection. Could you please try running pingr::is_online() to see if its working correctly?

Cheers,

Jeff

Hi Jeff, I am experiencing the same issue as Anke. While running wdpa_fetch() on a window machine I get the same error. As you suggested, I tried pingr::is_online() where I look incorrectly without an internet connection. The https://cran.r-project.org is inaccessible at the moment (I guess they are having server issues). I am wondering if this is the reason behind the error and if there is a way to overcome it...

update: I am now able to access https://cran.r-project.org from my browser but still pingr::is_online return a FALSE statement. I have been trying curl::has_internet() , nslookup() , and the method showed in https://stackoverflow.com/questions/7012796/ping-a-website-in-r and they all return positive statement. Maybe you have an idea what I am missing?

Looking forward to use Wdpar thank you so much for you help

Hi, I don't think this is related to the CRAN issues. I have an idea for fixing this though, so I'll push a new version to GitHub later today and we can see if this fixes the problem.

[jeffreyhanson]

Actually, if curl::has_internet works - we can just use that instead of pingr::is_online. Thank you for trying out other options!

[jeffreyhanson]

@neriiacopo, could you please try installing the developmental version of wdpar on GitHub (e.g. using the R code devtools::install_github("prioritizr/wdpar")) and try running the example code for wdpa_fetch (see https://prioritizr.github.io/wdpar/reference/wdpa_fetch.html) to see if it works for you?

[neriiacopo]

The examples work smoothly now! Thank you so much!

[ankemueller]

Does also work now for me, thanks a lot!

[jeffreyhanson]

Awesome - glad to hear it's working. I'll submit the new version to CRAN.

Hi Jeffrey,

I'm still getting the error that I do not have internet connection while running wdpa_fetch(). Following curl::has_internet tells me I am off line, but pingr::is_online() says (correctly) that I am online. It would be great if you could you help me out!!

I have downloaded the package both via github and via R directly, but both versions do not seem to work. I am using a windows machine if that makes a difference.

Thanks in advance for your response :) Coline

Hi @ColineBoonman,

Thanks for reaching out! Just to check, could you please try re-installing curl to ensure that you have the latest version of curl installed? If wdpar still fails after that, I can update it so that it will think there is an active internet connection if either pingr or curl indicate an online connection.

[ColineBoonman]

Thanks for your quick response. I have re-installed curl, and it still says I don't have an internet connection > curl::has_internet() [1] FALSE (while pingr gives the opposite response: > pingr::is_online() [1] TRUE).

When I load the wdpar library and run the following line: lie_raw_data <- wdpa_fetch("Liechtenstein", wait = TRUE) I get this Error: Error in wdpa_fetch("Liechtenstein", wait = TRUE) : data not found in download_dir, and no internet connectionto download it.

It would be great if you could include the test of both pingr and curl to check for internet connection!

[jeffreyhanson]

@ColineBoonman, I'm so sorry - I missed the GitHub notification email for your post. I'll work on updating this now and let you know when it's ready.

[jeffreyhanson]

@ColineBoonman, I've just pushed a branch with the new pingr + curl internet checks. Could you please try it out and see if that fixes it for you? You can install it with remotes::install_github("prioritizr/wdpar@int-check").

[jeffreyhanson]

@ColineBoonman, I just wanted wanted to follow up and check if those updates fixed the issue?

[ColineBoonman]

I am sorry for my late response. It works now!! Thank you so much!

[jeffreyhanson]

No worries - thanks for confirming that it works now! I'll merge the fix into the main branch.
