It works fine.
But when we sync files there are on PC'S (Win98, Win 2000, XP, NT) only changed files have the Archiv-Flag

Interactive plot (histogram) in R..........possible?
Dear all,
I am looking for some kind of interactive plot to draw a histogram for a
normal distribution with different sample size. In that plot there would be
some sort of "scroll-bar" which will take min value 10 and maximum value of
10,000 as sample size (n) from a standard normal distribution.
In that case user will scroll in that scroll bar and histogram with
different sample

how do I make a movie out of a timeseries of 2D data?
Hi all,
I have an array of 10000 x 200 x 200 numbers... which is a time-series of
200x200 2D data...
The 1st dimension is the time index.
Is there a way to make a movie out of these data - i.e. playback 10000
frames(200x200) at a playback rate per second?
Thanks a lot!
