knit_env

This function makes the environment of a code chunk
  accessible inside a chunk.

This package provides a general-purpose tool for dynamic
        report generation in R, which can be used to deal with any type
        of (plain text) files, including Sweave and HTML. The patterns
        of code chunks and inline R expressions can be customized. R
        code is evaluated as if it were copied and pasted in an R
        terminal thanks to the evaluate package (e.g. we do not need to
        explicitly print() plots from ggplot2 or lattice). R code can
        be reformatted by the formatR package so that long lines are
        automatically wrapped, with indent and spaces being added, and
        comments being preserved.  A simple caching mechanism is
        provided to cache results from computations for the first time
        and the computations will be skipped the next time.  Almost all
        common graphics devices, including those in base R and add-on
        packages like Cairo, cairoDevice and tikzDevice, are built-in
        with this package and it is straightforward to switch between
        devices without writing any special functions. The width and
        height as well as alignment of plots in the output document can
        be specified in chunk options (the size of plots for graphics
        devices is still supported as usual). Multiple plots can be
        recorded in a single code chunk, and it is also allowed to
        rearrange plots to the end of a chunk or just keep the last
        plot. Warnings, messages and errors are written in the output
        document by default (can be turned off).  Currently LaTeX, HTML
        and Markdown are supported, and other output formats can be
        supported by hook functions. The large collection of hooks in
        this package makes it possible for the user to control almost
        everything in the R code input and output. Hooks can be used
        either to format the output or to run a specified R code
        fragment before or after a code chunk. Most features are
        borrowed or inspired by Sweave, cacheSweave, pgfSweave, brew
        and decumar.
