rnwString functions

The rnwString functions make knitting PFDs a bit more userfriendly.

The sanitizeLatexString function sanitizes a LaTeX string by escaping special characters. It is strongly based on the function described on http://stackoverflow.com/questions/5406071/r-sweave-latex-escape-variables-to-be-printed-in-latex by Aaron Rendahl.

rnwString.initiate(studyName, authorName, docClassArgs = 'a4paper,portrait,11pt', newPage = TRUE, pageMargins=15) rnwString.terminate(rnwString) rnwString.generate(rnwString, rnwPath, fileName, pdfLatexPath, envir = parent.frame()) sanitizeLatexString(str) hasLaTeX(pdfLatexPath)
The name of the study - used as the title of the PDF.
The name of the author(s) - also inserted on title page of the PDF.
Default arguments for the document class in LaTeX. For example, to use landscape pages, this should be 'a4paper,landscape,11pt'.
Whether to end the initiation string with a newpage command. This can be set to false if you want to add more information on the first page(s).
Margin of the pages in millimeters.
The rnwString to terminate or (after termination) generate.
The path where the temporary files (.rnw, .tex, etc) should be created. Use forward slashes. Note: the last character should not be a slash!
The filename to use for the temporary files. Omit the extension!
The path to PdfLaTex. This file is part of a LaTeX installation that creates a pdf out of a .tex file.

In Windows, you can download (portable) MikTex from http://miktex.org/portable. You then decide yourself where to install MikTex; pdflatex will end up in a subfolder 'miktex\bin', so if you installed MikTex in, for example, 'C:\Program Files\MikTex', the total path becomes 'C:\Program Files\MikTex\miktex\bin'. Note that R uses slashes instead of backslashes to separate folders, so in this example, pdfLatexPath should be 'C:/Program Files/MikTex/miktex/bin'

In MacOS, you can install MacTex from http://tug.org/mactex/ By default, pdflatex ends up in folder '/user/texbin', which is what pdfLatexPath should be in that default case.

In Ubuntu, you can install TexLive base by using your package manager to install texlive-latex-base, or using the terminal: 'sudo apt-get install texlive-latex-base' In ubuntu, by default pdflatex ends un in folder '/usr/bin', which is what pdfLatexPath should be in that default case.

The environment where to evaluate the expressions (normally the environment where the function is called).
The character string to sanitize.

rnwString.initiate starts an rnwString; rnwString.terminate closes it; and rnwString.generate takes an rnwString and creates a pdf.sanitizeLatexString returns the sanitized string.hasLaTeX checks pdfLatexPath to make sure pdflatex or pdflatex.exe exists.

  • hasLaTeX
  • sanitizeLatexString
  • rnwString.initiate
  • rnwString.terminate
  • rnwString.generate

### sanitize a string
newString <- sanitizeLatexString('this is a tilde: ~.');
### newString is now: "this is a tilde: \~."
