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,

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

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!

I have difficulty in installing package "snow" from

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,
Sebastian

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

(no subject)
hi all,
I wish to draw on the same graphic device 3 functions.
But i don't want them to be on different graph, i want to compare them on the same
I don't need mfrow or mfcol, I need something else...
1 graph on 1 device inside this graph 3 ploted function.
I saw something unsing data.frame, but i think it's overkill, and something less complicated must exist, if not why?

how to draw an ellipse
That's probably a stupid question, but I'm looking for a low-level
command which plots ellipse, specifying only center and deformation
axes. The purpose is to illustrate bivariates gaussians with 2D .95
confident levels without using any specific library.
Thanxs for your help,

Add lines to density plot
Dear List,
I am using R to learn bootstrapping concepts. Not to be oblivious to
the
contributed packages of boot and bootstrap, I have opted to do the
following as a way to hone my R skills.
One example I am trying to work through is the following:
x <- 1:20
Observed <- sample(x,20)
Resamples <- replicate(1000,sample(Observed,replace=TRUE))
Boot.Means <- apply(Resamples,2,mean)

Sort a data frame with respect to more than one variable
Dear All,
How can I sort a data frame with respect to more than one variable?
I know that for one variable X one may use: df[order(df$X), ] where df is the data frame containing X.
Many thanks,

red-black-green color palette?
I'm working on some heatmaps, and the person I'm working with would
prefer a red-black-green color palette (red denoting gene induction and
green denoting gene repression). Does such a palette exist already?
If not, is there an easy way to create one?
Thanks,
Jake
