I'm very new to R and I'm trying to construct a threaded binary tree using

helping.

Dear Lorenzo,
This is the trade off that comes with convenience. The `$` operator
passes its argument directly as I understand it. This is what lets
you pass unquoted names that not variables. The way around it is to

I would do it like this:
library(TeachingDemos)
tmp - dice(1, 2)
with(tmp, c(sum(Red==Green),mean(Red==Green)) )
plot(head(tmp,28))

Hi Dimitri,
The argument names may have changed. Notice that
melt.data.frame(smiths, measured = c(age, weight, height))
gives a message saying Using subject as id variables. This is
because measured variables need to be specified as measure.vars (or an
abbreviation of that: even m will work

If you have not installed it, it is probably not present yet. How to
check it: Well, that depends on your OS that is unstated so far.

Does anyone know of any packages or have any loose code for estimating the
intrinsic dimension of a data set?
Thanks for any leads,

Just to clarify to the OP (and please correct me if I'm wrong),
having to run as admin should only be needed when you have to *update*
(update.packages()) the so called recommend packages (comes with R)
that sits under 'Program Files'. If you don't run as admin and try
to *install*
