R version of SAS Proc Varclus
I am interested in finding an R version of SAS "Proc Varclus". SAS's Proc Varclus implements an oblique cluster analysis based on principal components. How can I find out if R has a package that runs the same algorithm implemented in SAS "Proc Varclus"?
Thank you,
Mary Helen Black

Orthoblique rotation on eigenvectors (SAS VARCLUS)
Hi All,
I'd like to build a package for the community that replicates the output
produced by SAS "proc varclus". According to the SAS documentation, the
first few steps are:
1. Find the first two principal components.
2. Perform an orthoblique rotation (quartimax rotation) on eigenvectors.
3. Assign each variable to the rotated component with which it has the
higher

Package for variable clustering
Dear R users:
is there a package, similar to varclus in SAS or varclus in S, ported or
written for R? Also, is there any other package in R that was designed
for
grouping the variables under different measures of distance (in cases
where data is non-Gaussian, autocorrelated, and so on).
Janusz.

"Missing links": Hmisc and Design docs
Hi folks,
Using R Version 1.6.2 (2003-01-10)
on SuSE Linux 7.2,
I just installed Hmisc_1.5-3.tar.gz and Design_1.1-5.tar.gz
These were taken from
http://hesweb1.med.virginia.edu/biostat/s/library/r
Checked the dependencies:
Hmisc: grid, lattice, mva, acepack -- all already installed
Design: Hmisc, survival -- survival already installed, so
installed Hmisc first
All seems to go

clustering question ... hclust & kmeans
I am using R 1.3.0 on Windows 2000.
For an experiment, I am wanting to find the most diverse 400 items to
study in a possible 3200 items. Diversity here is based on a few
hundred attributes. For this, I would like to do a clustering analysis
and find 400 clusters (i.e. different from each other in some way
hopefully). From each of these 400 clusters, I will pick a
representative. I expect

Variable selection in clusters using 1-R2 ratio
Folks,
I am looking for a means for calculating the 1-R^2 ratio for variable selection to mimic the values of PROC VARCLUS in SAS. While there may be better methods for variable selection, we are trying to duplicate published results at this time.
To date, I have been unable to find a way to obtain this value from Hmisc::varclus , stats::hclust and clustvarsel::clustvarsel. Can any of you give

cluster-analysis and NA's
Hi,
exist a special cluster-analysis algorithms
which can work with NA's.
a further "problem" is that i want cluster
variables not cases to identify special variable-set's.
Is it a common way turn the data.frame and use
kmeans,because this works with NA's, or have anybody another
method for finding "variable-sets" , with exception of factor analysis.
thanks for

SAS Import with sas.get {Hmisc} - status 127 error
I'm trying to import a .sas7bdat dataset into R with sas.get. I'm using

Non-Linear Optimization - Query
Dear All,
I couple of weeks ago, I’ve asked for a package recommendation for nonlinear
optimization. In my problem I have a fairly complicated non-linear objective
function subject to one non-linear equality constrain.
I’ve been suggested to use the *Rdonlp2* package, but I did not get any
results after running the program for 5 hrs. Is it normal to run this type
of programs for hours? Also,

Sweave for "big" data analysis
Hi,
Maybe I'm missing the point here...but let's suppose you are working with
"large" data sets and using functions that take a significant amount of time
to run in R. I woulnd't like to run these functions every time I call
Sweave("myfile.Rnw") within R. What is the "common" practice to use Sweave
in these situations. I would just run the function once,

Problem with effects package
Dear List,
Several times I use this package I get the error message shown below.
When I work out simple examples, it turns out to be fine, but when
working with real and moderate size data sets I always get the same

Do you know what could be the cause of the problem?

Sweave
Many of you are using Sweave for making statistical reports. I thought it might be helpful to some to see an example of the setup I use (in Linux). For those of you who have not yet discovered the power and productivity gains from using Fritz Leisch's wonderful package, I encourage you to give Sweave a try.

Problem with sas.get function in Hmisc
Thomas,
As F Harrel in a preceding message told me that you are the maintainer
of Hmisc package,
I write directly to you, with copy to the Rhelp list in case someone
encountered the same problem and find some benefit in the response.
I used quite often the function sas.get in Hmisc library which I is
very, very useful.
But, as trying to reuse it today it seems not to function anymore.

Simple R Question...
Let's say I have the data frame 'dd' below. I'd like to select one
column from this data frame (say 'a') and keep its name in the
resulting data frame. That can be done as in #2. However, what if I
want to make my selection based on a vector of names (and again keep
those names in the resulting data frame). My attempt is #4 but doesn't
work.

Avoid duplication in dplyr::summarise
Dear group,
Is there a way I could avoid the sort of duplication illustrated below?
i.e., I have the same dplyr::summarise function on different group_by
arguments. So I'd like to create a single summarise function that could be
applied to both. My attempt below fails.

Order of factors with facets in ggplot2
Hello,
I'd like to produce a ggplot where the order of factors within facets is
based on the average of another variable.
Here's a reproducible example. My problem is that the factors are ordered
similarly in both facets. I would like to have, within each facet of `f1',
boxplots for 'x' within each factor `f2', where the boxplots are ordered
based on the average of x

Error using the Rdonlp2 Package
Dear experts,
I'm attempting to solve a constrained optimization problem using the Rdonlp2
package.
I created a Lagrange function (L=f(x)-lambda(g(x)-c)), where x is a vector
of 16 parameters. This is what I'm using as objective function in the code
below. In addition, I set bounds on these parameters (par.u and par.l). When
I run the code, I get the error message shown below. Any idea
