Sometimes having problems finding a minimum using optim(), optimize(), and nlm() (while searching for noncentral F parameters)
Hi everyone.
I have a problem that I have been unable to determine either the best
way to proceed and why the methods I'm trying to use sometimes fail. I'm
using the pf() function in an optimization function to find a
noncentrality parameter that leads to a specific value at a specified
quantile. My goal is to have a general function that returns the
noncentrality parameter that

Including a single function from a package
Hello all.
I'm building a package where I want to include a function from two
different packages. In particular, I want to include mvrnorm and
hyperg_2F1 from MASS and gsl, respectively (but the specific functions
do not matter). With what I've tried after reading the "Specifying
imports and exports" section from the "Writing R Extensions" manual, I
get an error:

Problems with pf() with certain noncentral values/degrees of freedom combinations
Hello all.
It seems that the pf() function when used with noncentral parameters can
behave badly at times. I've included some examples below, but what is
happening is that with some combinations of df and ncp parameters,
regardless of how large the quantile gets, the same probability value is
returned. Upon first glance noncentral values greater than 200 may seem
large, but they are in

Modifying Internal C Files
Hi All.
I want to tweak a few minor things inside of internal C code. I have my
Win. XP machine set-up to build packages (including C code), but I'm
having problems getting the package to run correctly. In particular, I
want to modify a few things inside of pnbeta.c (namely errmax and
itrmax), which is what the pbeta() function calls upon when there is a
noncentral parameter. I copied the

The boot Package with bca Intervals and Inf and NaN Values in an Automated Function [mediation()]
Hi everyone,
I use the boot package within the MBESS package to automate much of
the hard part for folks interested in performing a (simple) mediation
model. The function mediation() works well, except for a (probably)
unrealistic artificial data set.
When I apply the bootstrap I sometimes get:
Error in t.star[r, ] <- res[[r]]
which is (I think) due to Inf and -Inf and NaN values produced for

Control variables in mediation analysis
Hi everyone,I would like to test a mediation model, that has several control variables. More specifically, I would like to test the indirect effect with bootstrapping. However, all the packages I have found so far (e.g. MBESS) only allow testing a simple mediation model (One independent, one mediator, one dependent) so that I cannot include any controls.
Can somebody help me?

Dream of a wiki GUI for R
Dear R fans ( and wiki fans),
I am just writing a draft to introduce confidence intervals of various
"effect sizes" to my students. Surely, I'll recommend the package
MBESS in R. Currently, it means I have to recommend R's interface at
first. As a statistics teacher in a dept of psychology, I often have
to reply why not to teach SPSS. Psychologists and their students hate

New package: mpt
Dear all,
I have submitted a new package called mpt to CRAN.
It contains functions for fitting and testing multinomial
processing tree (MPT) models, a class of statistical models for
categorical data that involve latent parameters. These parameters
are often interpreted as psychological processing variables.
An introduction to these models is:
Riefer, D.M., & Batchelder, W.H. (1988).

RExcel rcom Server Loading The Wrong Version of R
Hi,
I'm pretty new to R and VERY new to RExcel. I've just finished setting
it up and I'm having some problems. My first Issue is that if I attempt
to use a function like RApply("sum", A1:A4) from within excel it gives
me an error saying "There seems to be no R process connected to the
server" I can then see an R Console open up and I get a message saying R

Confidence interval for the coefficient of variation
Dear,
We are trying to determine the (one-sided) CI for the coefficient of
variation in a small sample (say n = 10), with mean 100 and standard
deviation 21.
It appears though that the R-function ci.cv() and our simulation do not
agree.
The R-code:
library(MBESS)
n = 10
ci.cv(mean = 100, sd = 21, n = 10, conf.level = 0.9)
U10.95 <- 0.3551754
ci.cv(mean = 100, sd = 21, n = 10, conf.level =

c2d4u: apt sees new package version as a downgrade
Hello,
I noticed a strange thing when attempting to upgrade a specific package (lavaan) from c2d4u and wondered if someone could confirm the problem. In short, apt seems to think that an older version from the "universe" repo is higher than the newer version from c2d4u.
When I do
apt-cache showpkg r-cran-lavaan
I get the output at the bottom of this email. Then, I tried to force
