How difficult is it to get a good feel for the internals of R, if you want
to learn the general code base, but also the CPU intensive stuff ( much of
it in C or Fortran?) and the ways in which the general code and the CPU
intensive stuff is connected together?
R has a very large audience, but my u

a new language that can produce complex statistical tables far faster,
with much less code and effort, than any previous statistical
programming language.
a version that outsources ( gives work to do ) to vilno data
transformation and R is already in beta mode, a version that
outsources to SAS/BAS
How do you do a double loop through a matrix or data frame , and
within each iteration , do a calculation and append it to a new,
second data frame?
(So, if your original matrix or data frame is 4 x 5 , then 20
calculations are done, and the new data frame, which had 0 rows to
start with, now has 2
Hello,
I have a question as to how the syntax for glht(package multcomp) and
estimable (gmodels) works, since I'm not getting everything from the
documents I've googled so far, especially with models with 2nd order
terms.
A modestly complex model:
2-way anova with one continuous covariate, no ran
It does, thank you. I was able to understand enough of it to do the

such as install.package() and the r-cran-foo build dependencies. (the

installing on Ubuntu, how to do it and have people found it to be glitchy?
which is easier , binary install or from source ?
With the source install, are you less likely to have a dependencies issue ?
( Ubuntu does the GCC install seamlessly, but has no mention of R )

Am I asking for too much:
for any object that a stat proc returns ( y <- lm( y~x) , etc ) ) , is there
a super convenient function like give_all_extractors( y ) that lists all
extractor functions , the datatype returned , and a text descriptor
field ("pairwisepval" "lsmean" etc)
That would just b

When you install from source ( which I can't , because I can't figure
out how to install GCC) , does the source install have binary
dependencies?

, if credible , would seem to suggest that there is no good reason to
choose Suse.
I really don't have time for such nonsense, maybe I'll just reinstall as Ubuntu.
Also, noticed that GCC was not installed when S
Can't figure out how the install works, it is certainly not automatic.
Also , the "Install" option on the R web site for Suse 11.1 does not work.
And the install software native to Suse, cannot figure out.
Does Suse have more problems installing software than Fedora or Ubuntu?
Or is this a hassle
Will R have more glitches on one operating system as opposed to
another, or is it pretty much the same?

It does look like Gentleman and Ihaka not only lied to the New York
Times, but also to the New Zealand Herald and who knows who else. This
is disgusting. The R programming language is the S programming
language, and Gentleman and Ihaka are not the ones who designed it.

Ashlee Vance's article on R in the New York Times.
This is typical of the New York Times. Because they get to coast on the
prestige and reputation of their brand , they have a history of just this
sort of journalistic sloppiness. Whether it's the author or the editor at
fault doesn't really matter
Hi,
Where can I find information ( freely available on the Internet , and also
books or other sources ) on how having sampling weights changes the
calculation of the standard error (of means and proportions)?
How good is R for this type of procedure? And SAS?
thanks
Robert
