Reports "Error: (converted from warning)"... appears to be ignoring some environment settings in appveyor.yml

[pcarbo]

It appears that something changed with Appveyor in the past week, because the Appveyor tests for my R packages tests were working fine up until a few days ago. It now appears to be ignoring some of the configuration in the YAML file. Do you have any idea what might be going on with Appveyor?

In my YAML file, I have (among other settings):

environment:
  global:
    _R_CHECK_FORCE_SUGGESTS_: false
    WARNINGS_ARE_ERRORS:

and yet Appveyor still reports (for the suggested packages):

Skipping 3 packages not available: ExtremeDeconvolution, flashr, mixsqp
...
Error: (converted from warning) packages 'ExtremeDeconvolution', 'flashr', 'mixsqp' are not available (for R version 3.5.1)
Execution halted
Command exited with code 1

The error only occured after I forced a re-build (no new commits).

See here for a full example of this. Any help or insight would be much appreciated! And I'm happy to provide more details to help isolate the issue.

@gaborcsardi Seems to be working! I don't quite fully understand what the issue was, but thanks! Maybe R_REMOTES_NO_ERRORS_FROM_WARNINGS should be mentioned somewhere in the README? I think others could benefit.

Regardless, feel free to close the issue as you see fit.
