RKWard on Windows
|This page has been marked as needing an improvement. This means the page is incomplete, badly structured or otherwise in need of significant improvements. Most importantly, a walkthrough for the installer is needed|
RKWard on Windows is still a very young project. We'd like to encourage you to give RKWard a try on Windows, but if you do, you should expect all sorts of issues, small and large. Please help us by reporting the problems you find.
(Please use the bug trackers to report issues. This section is only meant to document the major deficiencies.)
- There are several bugs related to file-selection dialogs. In some situations it helps to go to the KDE "system settings"->Advanced->Platform and deselect the "Use native filedialogs" option.
- Some users have reported that functions trying to download from the internet (e.g. package installation) will fail, in both R and RKWard on Windows. In this case, please try running "setInternet2(TRUE)" in the R Console after starting RKWard (as per ).
Standard installation: Complete installation bundle
The easiest way to install RKWard on Windows is using the binary installation bundle.
- Simply download the above file and double-click the downloaded .exe-file.
- You will be prompted for an installation folder. This could be C:\Programs\, but also a network share, a USB disk, or almost any other folder. A subdirectory "RKWard" will be created in this folder.
- You may want to drag-and-drop the "RKWard"-icon from the installation-folder to your desktop or to another easily accessible location.
That's all! For more information see http://sourceforge.net/projects/rkwardextras/files/Readme.html/download . At the time of this writing, the bundle includes RKWard 0.5.4, KDE 4.4.1, and R 2.11.1. If you want to use a custom installation of KDE and / or R, use the "RKWard on Windows installer", instead (see below).
Custom installation: RKWard on Windows installer
You need to install R and KDE before you can install RKWard.
A windows installer is available at http://cran.r-project.org/bin/windows/base/ .
Installation should be straightforward and does not require any special settings. In cases of doubt, extensive documentation is available from the same url.
Generic instructions for installing KDE on Windows are available at http://techbase.kde.org/Projects/KDE_on_Windows/Installation . For RKWard, proceed as follows:
- Download the KDE Windows installer and run it.
- Be sure to select MinGW4 as compiler mode on the third page of the installer.
- Install the following KDE packages:
- kdebase (in some versions of the installer, this is called kdebase-mingw or kdebase-apps and kdebase-workspace)
- (many additional packages will be installed, automatically).
The RKWard installer itself is available at https://sourceforge.net/projects/rkward/files/Current_Stable_Releases/install_rkward_0.5.5.exe/download . In the installer you will need to specify the R and KDE installation directories.
Updating R / KDE / RKWard
Updating RKWard itself
The easiest way to update RKWard itself in an existing installation is to simply use the RKWard on Windows installer, and to point it to the correct location. In general, the latest version of RKWard should work with all reasonably recent versions of KDE and R.
To update the KDE portion of an existing RKWard installation, you can use the KDE windows installer as described in the "Custom installation"-section, above.
- In general, KDE releases are "binary compatible" with earlier versions of KDE. Thus, in theory, updating KDE should not be a problem. In practice, we recommend to back up your KDE installation, first.
- As usual, you need to choose the MinGW4-compiler.
- We do intend to update the complete installation bundle for important new releases of KDE. So consider waiting until a complete installation bundle is ready, instead.
To update R, use the R installer.
- Often, new releases of R will work with old versions of RKWard, especially, for patch releases (those differing only in the third section of the version number), generally there should not be any problems. However, it is always a good idea to use the latest version of RKWard with the latest version of R. If in any doubt, back up your installation, first.
- You can either install R to the exact same location as before. In this case nothing special needs to be done. However, if your R installation path contains a version number, or is changed in any other way, then you will need to either
- Run the RKWard on Windows installer, again, after updating R or
- Open [Your\RKWard\Installation\]KDE\bin\rkward.bat in a text editor, and adjust the line that starts with "SET R_EXECUTABLE=" to point to the new installation path.
- Remember to update your R packages after updating R.
Compiling RKWard from source on Windows
Using emerge (recommended)
- Set up emerge as detailed, here: http://techbase.kde.org/Getting_Started/Build/KDE4/Windows/emerge .
This should be all you need to fetch rkward and all dependencies (including R). Note that this will take several hours to complete.
- Currently this has only been tested with the MinGW(4) compiler. You are encouraged to try compiling using MSVC, but quite likely you will run into some problems. Report those on the mailing list, and we will take care of them.
- At times, compilation using emerge will fail. If the build fails on the R or RKWard packages themselves, let us know on the mailing list. If the build fails at an earlier stage (qt / kdelibs / kdebase), you may want to check http://winkde.org/pub/kde/ports/win32/dashboard/ to see whether this is a problem with your particular setup, or a general problem.
- It is not easily possible to re-use an existing R installation in this approach. Should this be a hard requirement, please use the precompiled package, or try the instructions for fully custom compilation, below.
Custom compilation / Packaging (not recommended for most users)
For info on compiling RKWard of Linux/BSD/similar systems see Building_RKWard_From_Source. The same information basically applies on Windows - once you have installed all requirements. For more information, refer to the developers' notes on packaging RKWard for Windows.
