package dependency error on loading lme4
Hi all,
I recently (today) updated the Matrix package and installed the latticeExtra
package, but then when I tried to load the lme4 package, I got the following
error message:-

Rconsole wishlist
Hi all,
Wouldn't it be nice (??!!) if R automatically issued a warning message when
the R console buffer was about to fill so that you could save all your
output into a text file? (I know about sink(), but I think it would be good
to have an easier mechanism to save a complete record of messages and
function output). And on a similar vein, wouldn't it also be nice if R

cluster package
Hi list,
I am doing cluster analysis using the cluster package. I created a dendrogram using the function plot(agnes(myData)). When I try to change the sise of labels, it does not work. I tried cex = 1.5, etc. Nothing worked. Can anyone give me a hint on how to change the sise of the labels, as well as the sise of axes labels.
Thanks

Hidden Rhistory files
Hi all,
I've ecountered a problem in the last few days with my .Rhistory file
not being able to be updated when I quit an R session because its file
attributes under Windows have been set as "Hidden". Recently, I put the
following line in my global Rprofile file:-
history(max.show=Inf)
so that I automatically open the entire history file for a project when
I begin a session, but I

Just to follow up Don Driscoll's earlier post, can anyone please explain

RGUI Console settings
Hi all,
Would someone like to comment on the relation between the "buffer bytes"
and "lines" settings in the console settings? Are they interdependent?
If so, how? And why allow both to be tweaked? If not, what is the effect
of changing "lines", but leaving "buffer bytes" the same?
I wanted to be able to see more of some large outputs in my console, as

se.contrast ....too hard??? .... Too easy????? .....too trivial???? ...... Too boring.....too????????
Hi all,
Regular and avid readers of this column will know that Don Driscoll and
I have recently posted two messages requesting assistance concerning an
apparent failure of "se.contrast" to produce an se for a contrast. So
far, an ominous silence rings in our ears, but read on Gentle Reader,

cluster analyses
I'm clustering rather large data sets and would like to cut the dendrograms
to get a better view of specific components. I calculate the dissimilarity
matrix using daisy() because I have a mixture of variable types: factors,
ordered factors and numerical variables. If I want one dendrogram, I use
agnes() for the agglomerative nesting and pltree() to draw the dendrogram.
That way, I get the

mysterious (to me) automatic loading of packages when R starts up
Hello,
I have recently noticed that in one of my work areas, a number of packages
are automatically loaded without my explicitly requesting them to be loaded
(see below). This only happens in one particular workspace (located in a
folder). I suspect (without any real evidence) that this may be related to
my creating plots using the ggplot2 package earlier in this workspace.
I am running R 2.7.0

assigning cluster id in cluster package-reg.
Well, you don't give much of an example....
I'm replying CC to the R mailing list. Please ask questions there, rather
than adressing individuals for basic help.
Here is one; does it answer your question ?

plotting dendrograms from cluster analyses
Hi all,
I have a bit of a newbie question here that I hope y'all can help with. I've
run a cluster analysis using hclust on about 500 objects (using R1.3 under
Win 2000). The problem is that the tips of the dendrogram are so close
together on the plot that the labels overlap and are unreadable. I've used
"cex" to reduce the label sizes but this isn't sufficient with so

Dendrogram with the UPGMA method
Hi,
I am clustering objects using the agnes() function and the UPGMA
clustering method (function = "average"). Everything works well, but
apparently something is wrong with the dendrogram. For example:
x<-c(102,102.1,112.5,113,100.3,108.2,101.1,104,105.5,106.3)
y<-c(110,111,110.2,112.1,119.5,122.1,102,112,112.5,115)
xy<-cbind(x,y)

Is anyone aware of a function that outputs dendrogram ultrametrics?

hc2Newick is different than th hclust dendrogram
Hi R helpers... I am having troubles because of the discrepancy
between the dendrogram plotted from hclust and what is wrote in the
hc2Newick file. I've got a matrix C:
> hc <- hclust(dist(C))
> plot(hc)
with the:
> write(hc2Newick(hc),file='test.newick')
both things draw completely different "trees"...
I have also tried with the raw distance matrix D and

cutree with agnes
Hi,
this is rather a (presumed) bug report than a question because I can solve
my personal statistical problem by working with hclust instead of agnes.
I have done a complete linkage clustering on a dist object dm with 30
objects with agnes (R 1.8.0 on
RedHat) and I want to obtain the partition that results from a cut at
height=0.4.
I run
> cl1a <- agnes(dm, method="complete")

colored nodes in dendrogram
Dear list,
is there a way how to add information to internal nodes (branching
points) in dendrogram created via plot.agnes function (package
cluster)?
I wish to place colored circles on the nodes, but I don't know how to proceed...
I'll be grateful for any suggestion

RGUI crash when opening script in XP Home enviroment
If there is a helpfile open (f.e ?glm) and it is the top window, then
an exception error occurs (closing RGUI)
when I hit the open file button.
If the helpfile is not the top window (of the RGUI) I am able to open a

The RGUI is not closing complete there is a blank screen left which I
