Is it possible to run R from a tablet using Honeycomb (Android 3.0)?
At some point, smartphones and tablets will have browsers capable enough to run RStudio in its server mode via the browser. Currently, the latter demands too much in terms of newer GWT, Javascricpt, ... magic that it remains limited to (recent enough) desktop browsers; see here for a bit more on this.
You can always ssh out though. Connectbot is a capable ssh client for Android, and of course free. No graphs though.
I used Linux Installer from http://android.galoula.com/en/LinuxInstall/ (my Dezire Z was rooted beforehand), installed stable debian and R! on this Linux install. I`m not a Linux-geek and total time for installation (first time loop file size was insufficient, and I repeated the whole process) wass less than hour however.
