question about dataframe ("sensory") in PLS package
...uot;names(sensory)" command, I will get two names: "Quality" and "Panel". But
if I use "summary(sensory)" command, I will get information of five
columns for "Quality" and 6 columns for "Panel" (such as "Quality.Acidity"
"Quality.Peroxide"...). So when I use PLS regression, the function is
simply "Panel ~ Quality" (but it's actually multiple regression).
Does anyone know how to build such dataframe? Please share some
experience. Really appreciate the help!
Sincerely,
Jeny

I unscrew the casing, extract the disk platter(s), slide a very strong
magnet over both sides of the platter surface then bend the platter in
half.
How secure is that ?

I often find harddrives with several 10 mm drill-holes in them, in the
electronics disposal room at work.
I'd say that'd be enough as well. 8-)

I have seen a guy in the I.T. department where I work take a hard
drive....remove as many stickers from it (to make it porous as possible)
and then soak it in a "brine" of ammonia, hydrogen peroxide, bleach, and
salted water...for like a week or two. Afterwards? total useless junk.
