# #' Wrapper for knitr::knit
# #' 
# #' This function is merely a vectorized wrapper for knitr::knit.  It knits Rnw files into tex files.
# #' 
# #' @import knitr
# #' @aliases knitVector
# #' @export knitVector
# #' @author Jared P. Lander
# #' @param input Character vector of filenames (with path) to be knited.
# #' @param output Character vector of filenames (with path) for the output TeX.
# #' @param tangle Whether to tangle the R code from the input file (like Stangle)
# #' @param text A character vector as an alternative way to provide the input file
# #' @return The compiled documents are written into the output files, and the paths of the output files are returned.

# #' Wrapper for knitr::knit
# #' 
# #' This function is merely an advanced wrapper wrapper for knitr::knit.  It knits the Rnw files into tex only if the Rnw files are newer than the tex files.  Like LaTex, file names should not be provided with extensions as it will added them automatically.
