I have a couple of ideas - serialize() can store references (and some
simple assignment are just stored as references until one tries to
modify part of the copy, i.e. in a copy-on-write manner); ocassionally,
it will also store the package name as an attribute to the class name in
which the class

Gabor, I'm afraid it doesn't count! (Though I didn't
exclude it explicitly). I'm not interested in the behaviour
of the sequence with denominator = 7 particularly.
The system is in fact an examp

Thank you very much for explaining this. I had indeed overlooked the
use of encoding in 'file'. I also appreciate how unsatisfactory
guessing at the encoding can be, and that scanning the entire file is
not appropriate for large files or general connections.
Sorry that 'burden' came across as nega

From ?corRatio:
Letting d denote the range and n denote the nugget effect, the
correlation between two observations a distance r apart is
(r/d)^2/(1+(r/d)^2) when no nugget effect is present and
(1-n)*(r/d)^2/(1+(r/d)

I think you need to delimit a bit more what you want to do. It is
difficult in general to tell what encoding a text file is in, and very
much harder if this is a data file containing only a small proportion of
non-ASCII text, which might not even be words in a human language (but
