### VARIOUS METHODS USING R

%.rmarkdown.html : %.md
	### rmarkdown::render()
	cd $$(dirname $<); Rscript -e 'rmarkdown::render(basename("$<"),output_file=basename("$@"))'

%.markdown.html : %.md
	### markdown::markdownToHTML()
	cd $$(dirname $<); Rscript -e 'markdown::markdownToHTML(basename("$<"),output=basename("$@"))'

%.knitr.html : %.md
	### knitr::knit2html()
	cd $$(dirname $<); Rscript -e 'knitr::knit2html(basename("$<"),output=basename("$@"))'

%.pander.html : %.md
	### pander::Pandoc.convert()
	# note that pander silently modifies input markdown file
	# AND doesn't provide a way to set the output file
	# so this WON'T work with files with images in
	cd $$(dirname $<) && \
		TEMPFILE="$(addprefix _pander_,$(<F))" && \
		cp $(<F) $$TEMPFILE && \
	   	Rscript -e 'f.out <- pander::Pandoc.convert(f="'$${TEMPFILE}'",open=FALSE); file.copy(f.out,basename("$@")); unlink(f.out); cat("$@","\n")' && \
		rm $$TEMPFILE
