Fwd: col.axis
I need a help in the following code. I could not find any hint at the help
files
m <- c( 58, 47, 51, 57, 48)
plot(1:5, m, pch=19, col=1:5, axes=FALSE)
axis(1, at=1:length(m), labels=LETTERS[1:5], col.axis=2)
The labels A B C D E appear in this case with the red color.
What I really want is that thay get the same color as the circles, but if I
try the line

mtrace function
I use windows xp. When trying to use the function mtrace from package debug
the window that should open with the function to be debugged do not show
any text at all. It shows only a part of my desktop. Does anyone know why.
Is there any imcompatibility between windows xp and debug package.
Thanks in advance.

We want to announce the Package ScottKnott now implemented at CRAN. The
package uses the SkottKnott clustering algorithm to perform multiple
comparison tests of means using the following experimental designs:

Parameter col.axis
I have a very short question.
Is there any possibility to give to the parameter "col.axis" of graphics
function "axis" a vector value of many colors instead of just one color,
otherwise is there any way around it?
Thank you very much

R- Package - fdth
We wish to announce the new package:
fdth - Frequency Distribution Table and Associated Histogram.
The package contains a a set of high level function which easily allows the
user
to make a frequency distribution table (fdt) and its associated plots.
The fdt can be formatted in many ways which may be suited to publication.
The plot (S3)
can be histogram, polygons or density, which can be dealt

mca-graphics: all elements overlapping in the help-example for multiple correspondence analysis
Dear all,
I tried out the example in the help document for mca (the multiple correspondence analysis of the MASS package):
farms.mca <- mca(farms, abbrev=TRUE)
farms.mca
plot(farms.mca)
But the graphic that I get seems unfeasible to me: I cannot recognize the numbers (printed in black) because they are all overlapping and concealing each other. I don ?t dare using my own data, which

dissimilarity matrices
Dear All,
I have a dissimilarity matrix which I happily convert to a distance object
by running:
X <- as.dist(Y)
and I can happily now run either hclust(X) or agnes(X).
So that the various bits of output are labelled correctly I would dearly
like to be able to give names to the columns and rows of X, as would happen
if I ran:
mydata<-read.table("clipboard",header=T)

cluster analysis using Dmax
Dear All,
a long time ago I ran a cluster analysis where the dissimilarity matrix used
consisted of Dmax (or Kolmogorov-Smirnov distance) values. In other words
the maximum difference between two cumulative proportion curves. This all
worked very well indeed. The matrix was calculated using Dbase III+ and
took a day and a half and the clustering was done using MV-ARCH, with the
resultant

Correspondence analysis/optimal scaling with ordinal variable
Dear R specialists,
I have a multivariate statistics question that I want to submit to
the R community (which conveys a very good statistical knowledge).
I need to perform an optimal scaling based on a discrete variable and
an ordinal variable. The discrete variable, Area, defines a
geographical area. The ordinal variable, EducationLevel, describes
the education level of individuals (the

Summary: Wanted: online Introduction to R
I agree with the the comments below on "Numerical recipes".
We developed some commercial software using the code and
tried to get a licence. They never responded to our corresponce :-)
We also mailed them fixes to some bugs !!! but never heard anything.
So we threw their code away and wrote our own...
it was a waste of time using the book.

[OT] correspondence analysis w/ non-mutually-exclusive categories
Greetings, again. This is not strictly an R question, so please feel free
to ignore it if you like.
My question is about the substance of correspondence
analysis. Specifically, is it appropriate to use ca on a matrix of values
such that the columns and/or rows are not mutually exclusive? To be more
detailed:
- The standard use of ca is illustrated in the example of corresp() (from
MASS):

Splitting variables
Dear R Users,I have a data set with several variables. One of these
variables is the number of farms per county and I'd like to split this
variable into two domains: (a) counties with fewer than 600 farms and (b)
counties with 600 or more farms
I've tried solving this problem for hours, but I'm new at R so I'm not
getting there.

Hi,
Maybe you can help me.
Im trying to join one NT Server 4.0 Remote Access Server to a samba PDC
(2.2.2) Domain so that the users who make dial-up connections can be

Building Samba 4 - Includes.c missing?
Hello all,
I've been peacefully using Samba 3 for about 3 years now, and it has done a wonderful job in my little world as domain member servers for file and print serving. Much bettetrver farms that some of my peers in the company are using.
So I want to try Samba 4 and see if I can play with making it my PDC. The only problem is that when I go to make, I receive the following error:
