the graph gallery strikes back
Hello useRs and helpRs,
Some time ago, in a gallaxy far away (here is the thread :
http://finzi.psych.upenn.edu/R/Rhelp02a/archive/46532.html ) we
discussed about a graph gallery showing the power of R in that domain. I
did some work around that, and there is a (pretty advanced) draft here :

For instance, there are some of my graphs,

how to print a data.frame without row.names
Dear All,
is there a simple way to print a data.frame without its row.names?
example:
datum <- as.Date(c("2004-01-01", "2004-01-06", "2004-04-12"))
content <- c('Neujahr', 'Hl 3 K.', 'Ostern')
df1 <- data.frame(datum, content)
print(df1)
datum content
1 2004-01-01 Neujahr
2 2004-01-06 Hl 3 K.

assignment of inidividual variables from spss save files
New to R, can't afford SPSS!
Why can't I assign spss variables? Here are the details.

Help in Overlaying of 2 Plots on the same Device.
I'm trying to overlay a density plot on a previously plotted histogram. However, i need to use the same axis as of the 1st(histogram) plot to plot the second. My second plot is creating its own axis and causing my plot to extend the entire histogram instead of getting a subplot on a portion of the histogram. I tried 'fig' and 'new' parameters with no luck.
Thanks in advance.

use of color for hclust
Hi,
I have a grouping of some observations. I want to cluster them using
hierarchical clustering and compare how the hierarchical clustering shows up
vis-a-vis the groupings. Is it possible to do this in color? I guess what I am
looking for is a way to color the labels of a hierarchical clustering plot
using different colors according to the original grouping. Any suggestions?
Many thanks and

about cutree
Hi Everyone,
I'm trying to use cutree to get the clusters after hclust. What I used is: mycluster<-cutree(cnclust,h=0.5)
Now, my problem is, how can I get the actual clusters? Thanks!
Best,

Putting different colors on labels in plot (hclust)
Hi All R-helpers
This is my first (but probartly not last ;-) mail to R-help, so hello to everybody.
My problem: Is there a way to give colors to the labels (sample labels) in plots for a hclust object for better visualization?
I have looked through plot, points, hclust and more but cannot find anything on label color. Anybody know if this is doable?

calculate phase/amplitude of fourier transform function in R
I did a fourier transform on a function in time domain to get the following
functions in frequency domain (in latex):
$Y_1[\omega] = \frac{1}{1-\phi_1 e^{-jw}}$
$Y_2[\omega] = \frac{1}{1-(\phi_1 + \phi_2)e^{-jw} +\phi_1\phi_2e^{-2jw}}$
How do I find the spectrum of this function for given $\phi_1$ and $\phi_2$
coefficients and in the discretization interval $w = [-\pi:.1*\pi: \pi]$?
Then, how

Hosting a R Graph Gallery?
Dear R users,
Following some of the recent questions and discussions about the R
plotting abilities, it occurred to me again that it would be very
valuable to have an R graph gallery.
Eric Lecoutre made a very nice example in:
http://www.stat.ucl.ac.be/ISpersonnel/lecoutre/stats/fichiers/_gallery.pdf
It would be very useful to many beginners, but probably also advanced
users of R, to have an

Fitting ARMA model with known inputs.
Hello!
Is it possible to use R time series to identificate a process which is
subjected to known input? I.e. I have 2 sequences - one is measurements
of black box's state and the second is the "force" by which this black
box is driven (which is known too) and I want to fit thist two series
with AR-process. The "ar" procedure from stats package expects that the
force is

Plot Problem
Hi folks,
I try to plot a variable which contains string-variables. it works, but the
problem is that there are a lot of values at the x axis (up to 24)
SO i have to scale or rotate the label at the x axis.
I tried this with the text() function. It doesn't work correctly.
Is there a simple way to rotate the labels?
Best regards,

matrix
hi,
is it possible to create a matrix with one row and according to add a row?
in fact, at present, I'm doing an algorithm which fill a matrix.
On the web site of CRAN, the package basic is impossible to be load!
can you tell me where i can found it!

Graph with values of coordinates of points in x axis
Hi all,
I want to draw a line with the values of x marked in X axis.
I tried with
x <- c(0,6,12,18,24,30) #coordinates of points x
y <- c(2,5,7,5,7,16) #coordinates of points y
plot(x,type="n",xlab="Months",ylab="Y
values",main="main",ylim=c(0,16),xlim=c(0,30))
lines(x,y)
The graph shows by default an increment of the sequence in x axis that

I saw something unsing data.frame, but i think it's overkill, and something less complicated must exist, if not why?

R: histograms and ylim
hi all
a very simple question once again!!!
can we change the "y" range in a histogram?
e.g.
x=rnorm(1000)
hist(x,ylim=0.5,prob=T) #this does not work
any suggestions???
