[R-pkg-devel] Vignette with error=TRUE chunks fails CRAN checks on r-oldrel-macos

[Roland Fuß]

Hi,

We are seeing this with our ALFAM2 package: 
https://cran.r-project.org/web/checks/check_results_ALFAM2.html

We have many code chunks with knitr option `error=TRUE`. My 
understanding is that CRAN machines should have set 
`_R_CHECK_VIGNETTES_SKIP_RUN_MAYBE_=true` and not check the tangled code 
but I see:

"When sourcing ‘ALFAM2-start.R’:

Error: Missing value(s) in predictor variable(s)

    See above for variables.

    Check these rows: 3

Execution halted"

Before I dive deeper into this and we maybe switch to `eval=FALSE`, is 
my understanding wrong? Or is the setup on the oldrel-macos machines 
different?


Thanks in advance,

Roland
