Flash Gordon: May 8, 2006; Death To Ming

I'm using Spacemacs and despite it having an ess layer I'm having trouble getting it to play nicely with .Rnw files. There doesn't seem to be a easy command that will knit the file and create a pdf. I am trying to put something in my user config so that I can just type SPC-m-o-c and it will run the commands:

code:

Rscript -e "library(knitr); knit('filename.Rnw')" && pdflatex filename.tex

but I can't seem to get it to work. Here is what I currently have, it gives me an error about 'wrong type argument: stringp, nil'.:

code:

  (add-to-list 'auto-mode-alist '("\\.Rnw\\'" . Rnw-mode))
  (defun custom-knit ()
    (let ((rnw-file))
      (setq rnw-file (buffer-file-name))
      (concat "Rscript -e \"library(knitr); knit('" rnw-file
              "')\" && pdflatex " (file-name-base buffer-file-name) ".tex")
      )
    )
  (spacemacs/set-leader-keys-for-major-mode
    'Rnw-mode "moc" (shell-command (custom-knit)))

EDIT: Alright, got it working by adding the following two items to my .spacemacs:

code:

;; in user-init()
  (setq ess-swv-processor "knitr")
  (setq ess-swv-pdflatex-commands (quote ("pdflatex" "texti2pdf" "make")))

;; in user-config()
  (spacemacs/set-leader-keys "moc" '(lambda () (interactive)
                                      (ess-swv-PDF "pdflatex")))

I still need to manually start an R instance when I open up a .Rnw file (and it doesn't seem to switch to the proper major mode automatically) but it's close!
