Vignette creation on package build fails with the error "Failed to locate the ‘weave’ output file"

Question

I've written an R package, which lives here and contains a vignette intended to step users through the rationale behind the package and how to best use it.

Unfortunately, on an attempt to build a source or binary package, the vignette construction fails with the following error:

* creating vignettes ... ERROR
Error: processing vignette 'session reconstruction.Rmd' failed with diagnostics:
Failed to locate the ‘weave’ output file (by engine ‘knitr::rmarkdown’) for vignette with name ‘session reconstruction’. The following files exist in directory ‘.’: ‘session reconstruction.Rmd’, ‘session_clusters.png’, ‘session_reconstruction.html’
Execution halted
Error: Command failed (1)
Execution halted

Exited with status 1.

Version information on the machine I'm building on:

$version.string

I've googled around and there doesn't seem to be a "proper" diagnosis: people have reported encountering similar errors, normally fixed with an upgrade to R 3.1.0 (which I'm using. Well, past using). Can anyone help me out?

Answer 1

I did not fully investigate the problem, but it seems that removing the spaces in the filename solves the problem.

Answer 2

I ran into a similar problem so I came to this site. I had constructed a vignette "Intro to XXX.Rmd", which failed. I changed the file to "Intro_to_XXX.Rmd" and R CMD check (CMD/Shift E in RStudio) worked.
