Error when running setup_r5 without internet connection

[jamaps]

Hi there! Great work overall on this library. It's been super helpful for some of my own work.

I'm currently trying to setup R5R on a server without internet for the first time (in order to link with individual level data) and I'm running into the following error:

> r5r_core <- setup_r5(data_path = "data", verbose = FALSE)
Error in curl::curl_fetch_memory(url, handle = handle) :
  Failed to connect to www.ipea.gov.br port 443: Bad access

Is there a way to bypass this connection check. I don't think I should need to connect to anything since I already have all my input data stored locally. But I might be misunderstanding what this connection is for.

Thanks!

Hi @jamaps.

The first time you run setup_r5, it downloads R5's Jar file from our server. Since that file has 46MB, it can't be included directly in the package on CRAN. Technically, you can manually copy the r5-v6.2-all_20210408.jar file from a working installation of r5r to the jar folder in your server.

Super, thanks! I'll give that a try.

Hi @jamaps. Checking into this issue, we found out that setup_r5 still tried to download a metadata file from our server, and didn't work when no internet connection was available. I've added the required file to the repository so there is a backup version to use when running offline.

If you install the latest development version from GitHub, it should work offline. You still need to manually copy the main R5 jar (r5-v6.2-all_20210408.jar).

Thanks @mvpsaraiva! got it working by manually copying in the R5 jar file as suggested.

I'm glad it works!
Thanks for using our package.

Hello, I couldn't find the jar file on the repository. Where can I access it? I get this error "Problem connecting to data server. Please try it again in a few minutes." when I try to run setup_r5r function. I thought that copying and pasting jar file manually would solve the issue. I'd be glad if you can help me with this. @mvpsaraiva

@hasanglr , what version of r5r are you using?

[hasanglr]

It is 1.1.0

[rafapereirabr]

Ok, this version of r5r v1.1.0 uses R5 V6.9. Here's the link to the JAR file. https://github.com/conveyal/r5/releases/download/v6.9/r5-v6.9-all.jar

Many thanks - that solved the issue.
