change pch in 3dplot, export graph
Hello I was wondering if anyone has been able to change the pch value for
points in 3dplot()? I am able to change point colors just not symbol types.
I have included a portion of my code below. I realize this won't work
outside of my script, but thought, maybe there is something obvious that I
am doing wrong. Also is it possible to utilize the interactive feature of

Using eval in multinom argument
Hi,
I am having difficulty entering a 'programmable' argument into the multinom function from the nnet package. Interactively, I can get the function to work fine by calling it this way:
z1=multinom(formula = class.ind(grp[-outgroup])~ (PC1 + PC2 + PC3), data=data.frame(scores))
However I need to be able to change the number of variables I am looking for in 'scores' and so am

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

Define column names to a series of data.frames
Greets to the list!
I am aware that this topic has been discussed several times. And I've
read quite some related posts [1]. Yet, can't seem to give a solution to
my problem.
I have 6 data frames consisting of 6 rows x 7 columns put together from
other data.frames.
Something like:
a b c d e f g

R and S-Plus got the different results of principal component analysis from SAS, why?
Dear Rusers,
I have met a difficult problem on explaining the differences of principal
component analysis(PCA) between R,S-PLUS and SAS/STATA/SPSS, which wasn't
met before.
Althought they have got the same eigenvalues, their coeffiecients were
different.
First, I list my results from R,S-PLUS and SAS/STATA/SPSS, and then show
the original dataset, hoping sb. to try and explain it.

prcomp - principal components in R
Hello, not understanding the output of prcomp, I reduce the number of
components and the output continues to show cumulative 100% of the
variance explained, which can't be the case dropping from 8 components
to 3.
How do i get the output in terms of the cumulative % of the total
variance, so when i go from total solution of 8 (8 variables in the data
set), to a reduced number of

plotting other axes for PCA
Hi R-community,
I am doing a PCA and I need plots for different combinations of axes (e.g.,
PC1 vs PC3, and PC2 vs PC3) with the arrows indicating the loadings of each
variables. What I need is exactly what I get using biplot (pca.object) but
for other axes.
I have plotted PC2 and 3 using the scores of the cases, but I don't get the
arrows proportional to the loadings of each variables on

Hi,
I am not sure if this is the right place to ask, so please forgive me if it''s not. I have read most
of the documentation regarding shorewall, and found it fairly easy to understand. I am in the
process of buying a new house, where I will have my own computer room and a new ISP. I would like to
use 1 to 1 NAT on the PC''s. I will hopefully be setting my my network as follows:

problem with lists...
Hi guys,
I am new to R, so sorry if my problem seems trivial.
Sometimes I encounter some lists, which I cannot index their components
with [ . ]
For instance the prcomp() function returns a 'prcomp' object whose
components are some 'lists'. the second component is a list that
comtains the following:

Condensed PCA Results
Hello all,
I'm currently using R to do PCA Analysis, and was wondering if anyone knew the
specific R Code that could limit the output of the PCA Analysis so that you
only get the Principal Component features as your output and none of the
extraneous words or numbers that you don't want.
If that was unclear, let me use linear regression as an example:
