code is too wide in the theme manual
update the theme LyX manual
do not allow special chars in markdown figures
row.names = NA in kable(); by default, row names of 1:nrow(n) are discarded
define a few highlight commands in preamble for the highlight engine
a new engine `cat`, per suggestion of Stephen Eglen
modify opts_chunk, and this will break your cache! I'm intentional, because syntax highlighting commands have changed
hide sanitize and external; show cache.vars
roxygenize
remove some extra white lines
tweak readme
bump version
when an error occurs, the traceback info will be uglified if I call process_tangle/group in this way
a new function knit_exit(); closes #524
roxygenize
bump version; hopefully this is the last patch version before v1.3
a word about the testing
update bib
okay, ripley starts to warn against quartz() and win.metafile(); let me grDevices:: so that codetools::findGlobals() cannot find them
use the more natural getFromNamespace() instead of get()
