se everyone to use Gnumeric then:
- entries such as 2005/06/08 are interpreted as date and show as
8/6/2005. but even if you change them to 8/7/05 for example they will
be written in the csv in your original format, with the change
included (i.e. 2005/07/08 here)
- en
s? Is there anything else that I
could compute?
More generally, am I totally wrong in comparing these two methods?
Are there some references particularly appropriate to this? (NB: I am
already hunting down the Kaufman, L. and Rousseeuw
book)
Thank you in advance for your help.

s the
coordinates vectors other than by "unrolling" the matrix in a
data.frame:
x y mat
1 1 0.125
1 2 0.1367
1 3 0.2345
and using mat ~ x*y ?
Thank you in advance. Sincerely,

and applying a function to each of its columns/variables appears to
me as something one would want to do quite often.

If you want a nice terminal replacement try iTerm (and tweak a bit
the appearance settings to make it easier on the eye). If you want a
very nice text editor (which can actually interact with RGUI or send
text to a Terminal

it will still be pixel based (zooming on it will reveal pixels while
it's not true with vector based formats).
