geojsonio seems vulnerable to PROJ 6

[rsbivand]

I'm running reverse dependency checks using sf from github adapted not to fail with PROJ 6 sf_0.7-4, and CRAN rgdal also adapted not to fail with PROJ 6 rgdal_1.4-3, but see that geojsonio fails with PROJ 6. The failures are deep inside testthat, so opaque. I attach the compressed R CMD check files (R 3.5.3).
failing_check.zip.

Could you please check on a system instance with PROJ 6? When PROJ 7 hits us in 10 months, sf and rgdal will follow, while trying to keep backward compatibility. The current adaptations are enough to keep things running with the completely revised projection metadata storage systems, but more changes will follow, diverging more from legacy.

Thanks, I'll have a look. All of those validate tests are a non-issue now as that function is now defunct in the development version and it's tests removed.

Is there a recommended way to use a particular version of PROJ on macos?

Thanks!

Sorry, have no OSX access, so can't check. PROJ has some hints here: https://proj4.org/install.html#install, untried. There may also be non-PROJ issues at my end because I was running the github master of sf and get different outcomes from Edzer, so instability is a more fitting description than an identified problem. PROJ is going to be unstable for some time, but that's mostly because it wasn't actively maintained for some years.

thanks. i'll have a look

Closing this. errors were only related to the validate fxn, which is now defunct
