function optimization: reducing the computing time
Dear useRs,
I have written a function that implements a Bayesian method to
compare a patient's score on two tasks with that of a small control
group, as described in Crawford, J. and Garthwaite, P. (2007).
Comparison of a single case to a control or normative sample in
neuropsychology: Development of a bayesian approach. Cognitive

psychometric functions
Hi,
I want to fit some psychophysical data with cumulative gaussians. There is
quite a convenient toolbox for matlab called 'psignifit' (formerly known as
'psychofit'). It allows the lower bound of the sigmoid to vary slightly from
zero, aswell as the upper bound to vary from one. with these two free
parameters, the fitted function is less sensitive to noisy data and
outliers.

Reverse seq
Hi all,
I thought I was not SUCH a nooby:)
How can I reverse a sequence/ vector?
i.e., turn
X <- 3 5 4 2 6 5 4 3 6
Into
X <- 6 3 4 5 6 2 4 5 3
I mean without looping and indexing.
There should be a very easy solution, shouldn't it?

Error message when calling t.test() and aov() with a factor variables
Hi all,
Just noticed that the error that arises when calling t.test() with factors could be a bit clearer:
> t.test(factor(c(3,1,2,4,3,5,4,5)), factor(c(2,1,2,3,4,5)))
Error in var(x) : Calling var(x) on a factor x is defunct.
Use something like 'all(duplicated(x)[-1L])' to test for a constant vector.
In addition: Warning message:
In mean.default(x) :

Compiling R-devel - missing some expected features (zlib, bzlib, lzma, PCRE)
Hi All,
I am compiling R-devel on Linux (Ubuntu 16.04.2) and that works just fine, but I am missing some of the expected features, as shown here:
https://cran.r-project.org/doc/manuals/r-devel/R-admin.html#Linux
In particular, after configure (using all defaults), I see:
R is now configured for x86_64-pc-linux-gnu

I was wondering if there was an elegant way to extend a require array.
To whit it would be wonderful to do somthing like this:
class one {
service { awesome:
require => [ File[one], File[two] ]
}
file {
one:

two:

}
}
class two inherits one {

A concrete type I/III Sum of square problem
Hi R-help members,
I have read a lot in the Archive about the "Type I" vs "Type III" sum
of square. I think I have read confusing post so
I want to have a clear idea of the problem.
Here is an example.
I have 3 groups of subjects of unequal sample size (G1 (n=7), G2
(n=7), G3 (n=4)).
for Each subject I have 4 measures corresponding to the crossing of
2 factor (A & B)

Natural vs National in R signon banner?
The R signon banner includes this statement:
Natural language support but running in an English locale
Should that not say 'National' instead of 'Natural'?
Meaning that LOCALE support is enabled, not that the interface understands
human language?
Please ignore this and forgive me if this is an inappropriate post. I am a
N00B in R.

txtProgressBar strange behavior in R 2.12.0
Hi,
I am running R 2.12.0 (windows).
example(txtProgressBar)
gives me some funny screen output with all kinds of special characters
appearing and disappearing. It's happening on two different mashines since
vs. 2.12.0. Is this a known issue?
Best,
Jalla

System of related regression equations
Dear all,
I would like to estimate a system of regression equations of the following
form:
y1 = a1 + b1 x1 + b2x2 + e1
y2 = a2 + c1 y1 + c2 x2 + c3 x3 + e2
Specifically the dependent variable in Equation 1 appears as an independent
variable in Equation 2. Additionally some independent variables that appear
in Equation 1 are also included in Equation 2.
I assume that I cannot estimate these two

Extract confidence intervals from rma object (metafor package)
Dear R-experts!
I am working on some meta-analysis using the metafor package. I would like
to extract values of the confidence intervals of the effect sizes of the
single studies from an rma object. Those values are printed out when
plotting a forest plot using the forest function on the rma object, however
I was not able to locate them.
Many thanks for your help!

Natural vs National in R signon banner?
The way it's phrased now makes it seem that English is not a Natural
language ("Natural language support *but* running in an English locale").
Why not just state: "running in an English locale" and leave it with that?
Better to leave something out than to be unclear (being correct formally
does not always mean being clear to all users).

metafor: including phylogenetic non-independence among species?
Hello, Is it possible to include information about phylogenetic relatedness
among species (when species are replicates for each study within a
meta-analysis) in a meta-anlaysis in the metafor package?
Alternatively, I wonder if the method f Lajeunesse 2009 American Naturalist
has been adopted in R in any fashion?

asin(sqrt((xi+1)/(ni+1)))). Hovewer, i
