Importing function that is previously imported by other package
Dear developeRs,
I encounter the following problem: in the current version of my package
FrF2, certain calls to a functioni do not work when package combinat is
loaded, because function combn from combinat masks the function from
utils that my package uses.
I tried to solve this issue by importing function combn into the
namespace of FrF2; I don't need to export it, I just want to use it

BBH2 and FrF2 packages
Hi R HELP,
I consider the 2^3 factorial experiment described at page 177 of
the book Statistics for Experimenters: Design, Innovation, and Discovery
by George E. P. Box, J. Stuart Hunter, William G. Hunter (BHH2).

Problem with correct usage of formula environment
Dear all,
I am working on a function formula.design that should automatically generate
reasonable lm formulae for a number of different designs. All works well as
long as all variables used are columns of the design data frame. For one
function, I would like to incorporate a dummy variable for center points
that is not a column of the design. Without this function, it would work
like this (at

i know that one should try and limit the amount of looping in R

the code cold be rewritten if we dont use the loops.

sysdata.rda vs. rda files in data directory
Dear developeRs,
my package FrF2.catlg128 holds large catalogues and is supposed to gain
additional ones. All the catalogues are intended for the user.
So far, the catalogues were stored in the data directory, and LazyData
was "no". I understand that this is not considered wise any more (if it
ever was), so that I want to change to LazyData "yes" with the next
release

Code find exact distribution for runs test?
I've been attempting to understand the one-sample run test for
randomness. I've found run.test{tseries} and run.test{lawstat}. Both
use a large sample approximation for distribution of the total number
of runs in a sample of n1 observations of one type and n2 observations
of another type.
I've been unable to find R code to generate the exact distribution and
would like to see how

Help on Full Factorial Design
Hi Everyone,
I found the doe.base package and the FrF2 package to do nice experimental
planning and I'm very happy about this tool I was looking for such a long
time.
But I still try to find out how to add center points to a full factorial
design. The FrF2-package has a center point option but is just supporting
fractional designs?
Is there a possibility to have center points within the

PCA - scores
I am running a PCA, but would like to rotate my data and limit the
number of factors that are analyzed. I can do this using the
"principal" command from the psych package [principal(my.data,
nfactors=3,rotate="varimax")], but the issue is that this does not
report scores for the Principal Components the way "princomp" does.
My question is:

In a package, I want to use PCA function. The structure I used follow this

pca analysis: extract rotated scores?

I'm unable to find an example of extracting the rotated scores of a
principal components analysis. I can do this easily for the un-rotated
version.

computing scores from a factor analysis
Haj
i try to perform a principal component analysis by using a tetrachoric
correlation matrix as data input
tetra <- tetrachoric (image_na, correct=TRUE)
t_matrix <- tetra$rho
pca.tetra <- principal(t_matrix, nfactors = 10, n.obs = nrow(image_na),
rotate="varimax", scores=TRUE)
the problem i have is to compute the individual factor scores from the pca.
the code runs perfect

SPSS R Factor v2.4.2
I am not an R-Head, hence I use nice utilities that integrate R into SPSS
I have SPSS v24, R3.20 and R3.40
I have run IBM SPSS R Integration which requires linking to R3.20
I have installed R Factor v2.4.2
This package requires 'polycor' library
Unfortunately, 'polycor' does not exist in R3.20

SPSS R-Menu for Ordinal Factor Analysis
Dear all,
I am trying to conduct an enhanced version of factor analysis with a
SPSS interface that allows to use R. This approach has been suggested in
the recent article:

Journal of Statistical Software 46, pp. 1-29.
My variables are ordinal-type and the tool of Basto allows to run

Same eigenvalues but different eigenvectors using 'prcomp' and 'principal' commands
Dear all,
I've used the 'prcomp' command to
calculate the eigenvalues and eigenvectors of a matrix(gg).
Using the command 'principal' from the
'psych' packageĀ I've performed the same exercise. I got the same
eigenvalues but different eigenvectors. Is there any reason for that
difference?

Confidence intervals for Sen slope in zyp-package
Hi,
I have a question about the computation of confidence intervals in the zyp package, in particular using the functions zyp.sen and confint.zyp, or zyp.yuepilon.
(1) I'm a bit confused about the confidence intervals given by zyp.sen and confint.zyp. When I request a certain confidence interval in the function, the R output seems to deliver another confidence interval, e.g. when I set

Factor Analysis Output from R and SAS
Dear Users,
I ran factor analysis using R and SAS. However, I had different outputs from
R and SAS.
Why they provide different outputs? Especially, the factor loadings are
different.
I did real dataset(n=264), however, I had an extremely different from R and
SAS.
Why this things happened? Which software is correct on?
Thanks in advance,
