I am trying to understand the behaviour of read.table() reading
delimited files (with header=TRUE and fill=TRUE) when there are more
(possibly spurious) columns than headings. I give below four small
data files, all of which have one or two extra columns added to one
line. Reading the first f
Hi,
My last word on this topic until I get a working external R package ...
The igroup code has now been validated both with and without NAs and
with and without removing them. Thanks to Bill, Tom, Thomas, and
everyone for your helpful comments and hints.
The results for my validation run a

This issue is probably to do with on-screen viewing of PDF files written
from R (2.3.1, Windows XP, RHEL 4), not with how the files are produced.
So the question is mainly to ask whether others have seen similar
behaviour, and whether a remedy is known.

Thanks very much - I followed your advice, and have tried a variety of
permutations (using ACML, and LAPACK). For the most part, I'm still
'playing' with multiple threads, but given the performance I'm getting

The R-devel version of R provides a pluggable BLAS, which makes such tests
fairly easy (although building the BLAS themselves is not). On dual
Opterons, using multiple threads is often not worthwhile and can be
counter-productive (Doug Bates has found some dramatic examples, and you
can see th

The difference between twm and metacity in gnome or other gnome
windows manager is that twm uses X11 core fonts whe

The key issue is inheritance. If you use a data frame with attributes then
you can inherit data frame methods without further definition,
e.g.
x <- structure(data.frame(a = 1:10), my.attr = 33,
class = c("myclass", "data.frame"))
dim(x) # inherit dim method
but if you do it this way

Kevin,
Whether or not the R core developers want to merge these functions in base
R, they would make a great little package on CRAN. That way others could
easily use them, and for yourself, the package automatically gets updated
with new versions of R. It sounds like you're done with the hard par
Hello!
I am writing code where I define objects with new class. When I started,
it was a simple data.frame with attributes, but it is getting more evolved
and I would like to hear any pros and cons to go for list structure,
where one "slot" would be a data.frame, while other "slots" would take ove

Hello,
I have to calculate some GARCH models, especially I need to compute a GJR which
I need to modify (add another covariable and a dummy). In addition to this I
will use a Skewed Student´s - t, for which I have to model the kurtosis and the
skewness parameter as a function of the conditional t
