It sounds like R Markdown, when tangling a vignette into an *.R file,
should provide additional wrapping for chunks with the error = TRUE
option set. Would a try({ chunk content }) suffice?

R CMD check relies on the tangled script not to crash, and there is
currently no such wrapping in the generated output:
