...nt default behaviour conveys a misleading and arguably useless summary, and I don't go with the argument that we should persist with it because it is simple to understand where the numbers come from.

Dear R-Developers, please find attached a set of drafted functions for flat file import and export, partially extending existing functions, partially completely written as new code. I thought you might be interested in those functions and the accompanying utilities for padding and trimming. Main features are - supports several formats, i.e. fixed width and CSV (with one exception) - supports

...are invisioning is a very compact distro with ffmpeg and no xine/gstreamer/mplayer. We are looking at developing a wrapper for ffplay that will present a basic GUI control box. We already have a tiny audio player called Pmusic, and a audio CD player called pCD, a tiny file format converter called wooFF and these use the 'ffmpeg' utility (amongst others). For video DVDs we are thinking of using Ogle, which is quite small. This post is getting a bit long, so I'll get to the point... Our plans based on ffmpeg results in incredible size savings, but I have one very big request: that the...
