Error building R package vignette. Error in if (idx > 0) sprintf("default-%s.tex) else "default.tex" : missing value where TRUE/FALSE needed

Question

I am building an R package.

==> devtools::document(roclets = c('rd', 'collate', 'namespace', 'vignette'))

Updating package documentation
Writing NAMESPACE
Loading package
.
.
.
Writing NAMESPACE
Updating vignettes
Rebuilding projectR.Rmd

I get the following error after this

Error in if (idx > 0) sprintf("default-%s.tex", template_versions[idx]) else "default.tex" : 
  missing value where TRUE/FALSE needed
Calls: suppressPackageStartupMessages ... create_output_format -> do.call -> <Anonymous> -> create_latex_template
Execution halted

Exited with status 1.

I am not sure what is causing the error. I thought because it calls roxygen2::roxygenize, it may be originating from there but the package doesn't contain this error message. Can someone please guide me in resolving this?

What version of `BiocStyle` do you have installed? – duckmayr Dec 27 '19 at 00:06 — duckmayr, Dec 27 '19 at 00:06

You are getting this error from a bug in older versions of BiocStyle. As part of the vignette processing in the version you have, the following line is run:

idx <- match(TRUE, version >= template_versions)

However, if version >= template_versions returns NA, then idx will also be NA. Then the if (idx > 0) check throws the error you got.

You can see the commit where they fixed this bug here, by changing the above line to

idx <- match(TRUE, version >= template_versions, nomatch = 0)

So, you need version 2.13.1 or later to avoid this bug. One way to do that could be to install from GitHub:

library(devtools)
install_github("Bioconductor/BiocStyle")
