Running pandoc (via rmarkdown in R) with a custom writer like so:

usr/local/bin/pandoc +RTS -K512m -RTS test.utf8.md --to /Users/noamross/Library/R/3.2/library/ehastyle/outbreak.lua --from markdown+autolink_bare_uris+ascii_identifiers+tex_math_single_backslash --output test.html --smart --email-obfuscation none --css /Users/noamross/Library/R/3.2/library/ehastyle/outbreak-template.css

I get the following error:

pandoc: Could not find data file /usr/local/Cellar/pandoc/1.16/share/x86_64-osx-ghc-7.10.3/pandoc-1.16/data/templates/default./users/noamross/library/r/3.2/library/ehastyle/outbreak.lua

I can confirm that /Users/noamross/Library/R/3.2/library/ehastyle/outbreak.lua exists. The long path to the pandoc directory is due to the installation being via homebrew, but it's the right path. Pandoc seems to not find the writer file and try to find it in the default directory instead.

I get the error when running pandoc directly in the command line, as well. Sometimes I don't get this error when I remove some of the other arguments, though I haven't been able to figure out exactly which combination does this.

Does the data file directory

pandoc: Could not find data file /usr/local/Cellar/pandoc/1.16/share/x86_64-osx-ghc-7.10.3/pandoc-1.16/data/templates/default./users/noamross/library/r/3.2/library/ehastyle/outbreak.lua

actually contain ..templates/default./ ... with the period after default?
