R-Sweave v2.2 by Gilbert Ritschard (gilbert.ritschard@unig.ch)

Support for R, Sweave and knitr

 - R-Sweave-8.zip   for WinEdt 8
 - R-Sweave-7.zip   for WinEdt 7
 - R-Sweave-6.zip   for WinEdt 6   (no longer supported, last version v2.1)
 - R-Sweave-55.zip  for WinEdt 5.5 (no longer supported)

 - R-support is based on the RWinEdt stuff (menu, highlighting,
   tool bar buttons). The support is here made available
   in a standard WinEdt session
   instead of running it in a limited stand alone WinEdt instance.

 - support (sweave.edt, menu, buttons, ...) for sweave, the R program
   which transforms LaTeX .Rnw files with R chunks into a LaTeX files
   with the R chunks replaced by their R outcome.
   
 - Since version v2.0, support for knitr (http://yihui.name/knitr/).

 - Since version v2.1, support for inverse search to .Rnw file.

For the macro to run correctly, the following R 
packages should be installed in your R system:

 - cacheSweave
 - knitr
 - markdown
 - tools
 - stringr

We also recommend to transfer the Sweave.sty file from the
c:\Program Files\R\R-x.xx.x\share\texmf\ directory to a directory
searched by your TeX system. Alternatively, you can add the above
directory in the list of paths that TeX will search.
In any of these two cases, add a \usepackage{Sweave} in the
preamble of your LaTeX document.

For inverse search you need a PDF reader supporting it. You also need 
to install Duncan Murdoch's patchDVI R library, which is available 
from R-Forge with the following R command (needs latest version of R)

install.packages("patchDVI", repos="http://R-Forge.R-project.org")


Most of the credit of the R-support goes to Uwe Ligges, the author of
RWinEdt. Many thanks to him for allowing me to reuse his material.

The update for WinEdt 6 has been done by Karl Koeller. The much nicer
button images in the WinEdt 6 version of the support are also due to
Karl Koeller. Many thanks to him for his invaluable contribution.

Karl also updated the winEdt 6 version for WinEdt 7.

Karl wrote the new install and uninstall procedures used for 
version 2.2 (R-Sweave-7 only) which should allow a smooth transition 
to WinEdt 8.  

The included RWinEdt stuff is under GPL-2 licence, thus we distribute
this R-Sweave support also under GPL licence.

Licence: GPL v2 or newer (http://www.gnu.org/copyleft/gpl.html)

      log when errors are reported.
    - there are also a menu item and a toolbar button to knit
      .Rhtml, .Rmd and .Rrst files (see http://yihui.name/knitr/ 
      for details and example files) and displaying the resulting 
      .html (from .Rhtml and .Rmd) with the default browser.
    - the installation can be done from any folder and the
      whole support is installed in %b by the install macro.

v1.2 Changes since v1.1

      ...\bin\i386    (for the 32bit version)
      ...\bin\x64     (for the 64bit version)
    the default installed setting is for bin\i386, you should change that
    manually if you want to use x64
    (see below how to pass registry to Sweave.edt and
    specially LetReg(7, ...))

=============================================================

v1.1 Changes since first version:
  - support and menu item for Stangle (for concatenating all chunks
    into a single .R file)

=============================================================

Installation Instructions:
=========================

There are specific zip file for each distribution: version WinEdt 7,
WinEdt 6 and one for older version, namely WinEdt 5.5. 
Just select the one which is appropriate for you.

!!! If you had a previous version of R-Sweave installed, be sure
!!! to delete all related items from mainmenu.ini and from
!!! toolbars.ini
!!! R-Sweave_uninstall.edt will do it only if you did not customize
!!! any items after installation !!

1. Unpack the R-Sweave.zip, preferably in an empty folder.

2. Open WinEdt.

3. Make a backup of your present configuration (using
   options/maintenance/backup).

4. Launch the "R-Sweave_install.edt" macro
   (For instance by opening this .edt file in WinEdt and
   pressing Ctrl-Shift-F9).

 In WinEdt 6 and upper, you will have two default drop-down buttons:
 one for Sweave and knitr, and one for R. This can
 indeed be customized.
 In WinEdt 5.5, you may add R-Sweave related buttons to the Tool Bar
 through the "Enter Tool Bar Setup..." dialog (contextual menu
 from the tool bar). However, you should first restart WinEdt to have
 access to the R-Sweave buttons.

Now, you should be done.

Default installation is for the 64bit version of R 2.12.0 or higher.

If you have only access to the 32bit version: Before insatlling, open
the MainMenu.ini file (or R-Sweave.dat file for the 5.5 version)
provided with the support and substitute in it all occurrences of
LetReg(4,'\x64') with LetReg(4,'\i386') or LetReg(4,'') if you have
an older version than R 2.12.0.

===============================================================

Usage instructions:
==================

You can customize the menu items.

Here are the arguments (registry) that can be passed to the
Sweave.edt macro:

LetReg(6,"xxx"); where xxx can be pdf, dvi, R, Stop, Direct 
                 the latter being an alias of pdf.

LetReg(7,"R installation path");
                 can be used to tell the macro where it can find
                 the R binaries. If empty, sweave.edt
                 uses the value given by the Windows registry.

LetReg(8,"xxx"); where xxx can be:
                 cache : for running cacheSweave instead of Sweave.
                 knitr : for running knitr instead of Sweave.
                 R : for running Stangle instead of Sweave.
                    Stangle just concatenates all chuncks into
                    a single %n.R file. Indeed when choosing this
                    option, the %!6 register will be ignored.

LetReg(9,"open"); When set, Sweave.edt just opens an R console.

LetReg(4,"yyy"); where "yyy" can be either "\i386" (32bit),
                 "\x64" (64bit) if you are running R version 2.12.0
                 or higher, or "" for R version < 2.12.0 .


Arguments that can be passed to knitr.edt are:

LetReg(6,xxx); where XXX can be pdf, dvi, R or stop
                 For files with extension .Rmd or .Rhtml:
                    when not "stop" or "R" knit outcome is 
                    processed and shown with 
                    default application for .html extension.

LetReg(7,"R installation path");
                 can be used to tell the macro where it can find
                 the R binaries. If empty, sweave.edt
                 uses the value given by the Windows registry.

LetReg(4,"yyy"); where "yyy" can be either "\i386" (32bit),
                 "\x64" (64bit) if you are running R version 2.12.0
                 or higher, or "" for R version < 2.12.0 .



================================================================

Good luck and enjoy.
