R garbage collection
...lled blocks as "roots"
for the garbage collector, so that transient blocks they reference stay
uncollected? So far I can only deduce that as long as the answer to my
first question is yes, I can bind an arbitrary symbol to them in the
global environment. Is this the best way?

data filtering
...f the elements?
The only thing I can think of is to use closures to write something like
a Lisp list "filter". Not sure on the readabilty merits, especially if
there is a direct way to do it. If Matlab had closures I know running
them in a loop would be a bear on runtime anyway.

reading large data
....
The same thing happens when I read the 100% sample in from an RDBMS with
RODBC.
For the time being I have worked around by feeding in small cross
sections 100% from the RDBMS, and storing a 10% whole sample in RAM.
But in the future it would be nice if I could just use the RAM in my
box.

setuid question
...create a file in this directory it shows it being owned by
the actual person who created it rather than the user specified in the force
user = line of the configuration...
I've tried to use chmod u+s but that doesn't seem to work..
Can anyone tell me how to achieve this?
Many thanks.

turning off automatic coersion from list to matrix
...ally. Can I turn
this off? Eg:
data.class(sapply(c("product","region"),function(i) {a[,i]}))
[1] "matrix"
whereas this would be acceptable to by=
data.class(list(product=a[,"product"],region=a[,"region"]))
[1] "list"
