R help - Sep 2008 - Installing R 2.7.2 on Windows with /LOADINF flag doesn't do anything

Hi

I want to install R from a script, so am following
http://cran.r-project.org/bin/windows/base/rw-FAQ.html#Can-I-customize-t
he-installation_003f.  

I first installed R with the /SAVEINF="r_install_config.txt" flag and
it
created a nice text file for me - perfect.

I then uninstalled R, and re-installed from DOS with:

R-2.7.2-win32.exe /LOADINF="r_install_config.txt"

Windows loaded up the installer anyway, and even worse, none of the
options I had changed were set in the installer, they were still the
defaults.

Am I using that flag incorrectly?!

Thanks
Mick

The installer is built with Inno Setup (see www.innosetup.com).  I just 
tried the lines above, and I see that some of the defaults are changed, 
but not all.  The "startup options" do not get saved in the file. 
These
are not standard Inno Setup settings, we customized them for R.

You can avoid the dialogs by using /SILENT or /VERYSILENT command line 
options.

I've asked on the Inno Setup newsgroup whether there is support for 
saving custom options in the INF file.  If so, I'll try to fix this for 
2.8.0.
