I've just committed some code to R-devel (currently the "alpha" version of 2.3.0) to allow users in the Windows Rgui to load settings from an Rconsole file while R is running. Currently this is done through the Edit|GUI preferences dialog (there's now a "Load" button); if I have time I'll also add a loadRconsole() function. This is intended to be used to switch between different Rconsole settings, e.g. large fonts for a presentation versus regular fonts for single-user purposes. Currently it can be done through environment variables, but those are sometimes hard to manage; this should be simpler. As we're now in the alpha phase coming up to the 2.3.0 release, I'd really appreciate it if users would test this (and all other new features; see the NEWS and CHANGES files). The alpha releases are being built daily and are available on CRAN. This feature should show up in the Mar 29 build. Duncan Murdoch
