\usage{
knit_global()
}
\description{
  This function makes the environment of a code chunk
  accessible inside a chunk.
}
\details{
  It returns the \code{envir} argument of
  \code{\link{knit}}, e.g. if we call \code{\link{knit}()}
  in the global environment, \code{knit_global()} returns
  R's global environment by default. You can call functions
  like \code{\link{ls}()} on this environment.
