[R-pkg-devel] Advice about non-replicable error in CRAN R CMD check

[Dueber, David]

When I submitted my package (BifactorIndicesCalculator: https://github.com/ddueber/BifactorIndicesCalculator) to CRAN, the automated checks returned an error for the development release of R in Windows. The log file is (https://win-builder.r-project.org/incoming_pretest/BifactorIndicesCalculator_0.1.0_20191020_051536/Windows/00check.log), and the error message is pasted at the bottom of this e-mail. I tried to replicate this error locally, on R-hub, and winbuilder, but to no avail. The log file from winbuilder is (https://win-builder.r-project.org/OJ4O68aeF9OG/00check.log)

I am not 100% sure what the error means, other than that some package (either MplusAutomation or a package it uses, or a package used by a package MplusAutomation uses) seems to be referring to a package named "scales" which does not exist. But I have no idea why I can't replicate the error, and certainly have no idea how to fix it. Any help/advice would be appreciated. Thanks!
