[R-pkg-devel] Error while checking if Pandoc is available

[Maëlle SALMON]

Furthermore, I think you can simply use 
rmarkdown::pandoc_available("1.12.3") to answer both questions (is pandoc available, is the particular version or a later version available).

Maëlle.

Hugh is correct. To clarify, update

if (!rmarkdown::pandoc_available() || rmarkdown::pandoc_version() < "1.12.3") {
  stop("'brinton' requires Pandoc v < 1.12.3 (https://pandoc.org/)")
}

The reason is that when using 'a || b', expression 'b' will NOT be
evaluated if 'a' is not TRUE.  In contrast, when you use 'a | b',
expression 'b' will be evaluated regardless of outcome of 'a'.

A good rule of thumb is: If you expect your OR or AND statements to
give a single/scalar TRUE of FALSE, use || or &&.  This is commonly
used in if(), and while() conditions.
