[R-pkg-devel] "no prebuilt vignette index" error

[Berry Boessenkool]

On my windows machine, I once installed qpdf to get things done, but I'm not sure if that applies here.

https://sourceforge.net/projects/qpdf/


Linking to source code is also possible online, by the way:

https://github.com/wch/r-source/blob/trunk/src/library/tools/R/QC.R#L6713

I use a little package to find such URLs from within R:

https://github.com/brry/rskey#funsource

Kind regards,
Berry

Subject: [R-pkg-devel] "no prebuilt vignette index" error

QUESTION:

I wonder how to address the error that I’ve quoted in the subject line?


DETAILS:

I am using R 3.4.1 to build the “oce” package, which helps with the analysis of oceanographic data.  It’s several years old.

Lately, when I submit the “oce” package to winbuilder using

        devtools:build_win(version=“R-devel")

the message

        Package has a VignetteBuilder field but no prebuilt vignette index.

is issued. I do not get this message with

        devtools::build_win(version="R-release")

Using

        rhub::check_for_cran()

I find that message for some machines, but not all of them.

My DESCRIPTION (https://github.com/dankelley/oce/blob/develop/DESCRIPTION) has

        VignetteBuilder: knitr

and also

        Suggests: knitr, rmarkdown

(amongst other suggestions).  The file (https://raw.githubusercontent.com/dankelley/oce/develop/vignettes/oce.Rmd)

        vignettes/oce.Rnw

has YAML

        ---
        title: "Oce"
        author: "Dan Kelley and Clark Richards"
        date: "`r Sys.Date()`"
        output:
          rmarkdown::html_vignette:
            fig_caption: yes
        vignette: >
          %\VignetteIndexEntry{Oce}
          %\VignetteEngine{knitr::rmarkdown}
          \usepackage[utf8]{inputenc}
        —

and in this YAML sequence, I’ve also tried replacing the second-last line with

        %\VignetteEncoding{UTF-8}

I downloaded R 3.4.1 and see at lie 6703 of

        src/library/tools/R/QC.R

that R wants to find a file named

        build/vignette.rds

and (sure enough) that file is not in the tarball that is created with

        R CMD BUILD oce

at the commandline, or with

        devtools::build()

from within Rstudio.  As an aside, the latter issues a warning

        Warning in tools:::.build_packages() :
          invalid value for '--compact-vignettes', assuming “qpdf"

I’m not sure how to proceed to solve the problem I state in the second sentence of this email. And I’m not even positive that it *is* a problem, since it does not occur on all test systems.

Does anyone have any advice for further tests?

I’m sorry this email is very long — I tried to be quite clear.
