Release knitr 1.25 · yihui/knitr

NEW FEATURES

Office outputs (e.g., rmarkdown::word_document) supports the following chunk options out.width, out.height, out.extra. Their behavior follows the behavior of Pandoc's link_attributes extention (thanks, @atusy, #1746).
The chunk option fig.process can be specified by a function with the options argument to read chunk options (thanks, @atusy, #1749).
For kable(format = 'latex'), a single string consisting of l, c, and r for the align argument also works now, e.g., knitr::kable(head(iris), 'latex', align = 'llcrr'). Previously it has to be a character vector of individual letters.

Reverted #1519 (which intended to fix #1487): the valign argument of kable(format = 'latex') meant to control the vertical alignment of the inner tabular environment, instead of the floating position of the outer table environment. A separate argument named position has been added to control the floating position (e.g., position = "!b").

The returned value of combine_words() is wrapped in xfun::raw_string() for pretty printing.

The output hook for render_sweave() failed to respect the chunk option results='asis' (thanks, Achim Zeileis, https://stackoverflow.com/q/57571790/559676).
Added the unit px to the chunk option out.width if its value is numeric (thanks, @chendaniely, #1761).
The chunk option dependson did not work for non-R engines (thanks, @nielsrhansen, #1601).
