CHANGES IN knitr VERSION 0.2

NEW FEATURES

  • added support for including child documents in a main document (like \SweaveInput{} but with different implementations); see http://yihui.name/knitr/demo/child/ (#92)
  • for inline R code, character results are returned as-is now (without \texttt{})
  • new function purl() as a wrapper to knit(..., tangle = TRUE) which extracts R code from the input document (thanks to Dieter Menne's wife who suggested the function name)
  • the error hook applies to inline R code when an error occurs in the inline R code, in which case knitr will not stop by default; instead, it writes the error message into the output (#85)
  • chunk option split also works for HTML output now using <iframe></iframe> (#82)
  • knit() gained an argument text as an alternative to input (#88)
  • new chunk option child to include child documents into the main document (#92)
  • chunk option external defaults to TRUE now (was FALSE by default in the last version)
  • added a new demo to show how to build package vignettes with knitr: http://yihui.name/knitr/demo/vignette/
  • added support to the quartz() device under Mac (#103); now the dev option has more choices (see http://yihui.name/knitr/options)
  • chunk option echo can take a numeric vector to select which R expressions to echo into the output now (#108); see http://yihui.name/knitr/options
  • a new function stitch() which is a convenience function to insert an R script into a template and compile (to quickly create a report
    based on an R script)
  • for a chunk hook to run, the corresponding chunk option no longer has to be TRUE; it can be any non-null values; this enables us to make use of the option value directly instead of only knowing it is TRUE (see http://yihui.name/knitr/demo/cache/ for an example)
  • knit() will no longer writes figure or cache files in the same directory as the input document; instead, these files are written in the current working directory (see ?knit)
  • a new function knit_env() that makes the environment of the current chunk accessible to the user

BUG FIXES

  • the code used to merge global chunk options and local options was buggy for cache; it has been fixed now, so cache is more stable (#105), but users may see previously cached chunks being re-evaluated with this version, which should be regarded as a normal phenomenon, and on the second run, the cached chunks will not be evaluated again
  • fixed a buglet when using both options out.width and out.height in Rnw (#113)
