Set regular expressions to read input documents
These are convenience functions to set pre-defined pattern lists (the syntax
to read input documents). The function names are built from corresponding
file extensions, e.g. pat_rnw()
can set the Sweave syntax to read Rnw
documents.
pat_rnw() pat_brew() pat_tex() pat_html() pat_md() pat_rst() pat_asciidoc() pat_textile()
The patterns object knit_patterns
is modified as a side
effect.
# see how knit_patterns is modified knit_patterns$get() pat_rnw() knit_patterns$get() knit_patterns$restore() # empty the list
