Thanks Brian.
Indeed, the vignette is in markdown form. When I updated my system to
R 3.1.3 I ran update.packages() and this seems to have upset things
(including R-studio processing of markdown files).
I tried removing rmarkdown and reverting to an older version so that my
sessionInfo() is

other attached packages:
[1] rmarkdown_0.3.3
loaded via a namespace (and not attached):
[1] digest_0.6.8 htmltools_0.2.6
I also made sure to remove all instances of rmarkdown before installing
the older version.
However,
R CMD build nls14
still gives lots of errors (these are related to content in the vignette
source and are, I believe, consequent on the warning about
engine$weave). The warning still refers to the later version of pandoc
which Ubuntu 14.04 repos don't yet have.
My current guess is some mismatch in the software infrastructure. I
have another machine with R 3.1.2 and rmarkdown_0.3.3 that manages to
build the package without complaint, but it would be good to get this
sorted out. Pointers on where to look for a fix are welcome.
