cluster analysis: "error in vector("double", length): given vector size is too big {Fehler in vector("double", length) : angegebene Vektorgröße ist zu groß}
Dear R Specialists,
when trying to cluster a data.frame with about 80.000 rows and 25 columns I get the above error message. I tried hclust (using dist), agnes (entering the data.frame directly) and pam (entering the data.frame directly). What I actually do not want to do is generate a random sample from the data.
The machine I run R on is a Windows 2000 Server (Pentium 4) with 2 GB of

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")

cluster a distance(analogue)-object using agnes(cluster)
I try to perform a clustering using an existing dissimilarity matrix that I
calculated using distance (analogue)
I tried two different things. One of them worked and one not and I don`t
understand why.
Here the code:

Clustering with 'agnes'
Hello,
I had a question regarding clustering using the agnes() function from the 'cluster' package.
I was wondering if anyone knew how I can identify cluster points after running the agnes function.
For example, I created a dataset with points randomly scattered around (0,0), (0,1) and (1,0). After clustering, the dendrogram shows all the clustered points and I get the ordering and

agnes clustering and NAs
Hello,
In the documentation for agnes in the package 'cluster', it says that NAs are allowed, and sure enough it works for a small example like :
> m <- matrix(c(
1, 1, 1, 2,
1, NA, 1, 1,
1, 2, 2, 2), nrow = 3, byrow = TRUE)
> agnes(m)
Call: agnes(x = m)
Agglomerative coefficient: 0.1614168
Order of objects:
[1] 1 2 3
Height (summary):
Min. 1st Qu. Median Mean 3rd

New to R, trying to use agnes, but can't load my ditance matrix
Hi,
I'm mighty new to R. I'm using it on Windows. I'm trying to cluster using a
distance matrix I created from the data on my own and called it D10.dist. I
loaded the cluster package. Then tried the following command...
> agnes("E:D10.dist", diss = TRUE, metric = "euclidean", stand = FALSE,

Clustering
Hello all!
I am performingsome clustering analysis on microarray data using
agnes{cluster} and I have created my own dissimilarity matrix according to a
distance measure different from "euclidean" or "manhattan" etc. My question
is, if I choose for example method="complete", how are the distances
between the elements calculated? Are they taken form the dissimilarity

Is there a function in R that is an equivalent of zoom in matlab? This is
very useful for being able to magnify details in a plot.
I have searched the help for "zoom", "interactive zooming", and "magnify".

agnes() in package cluster on R 2.14.1 and R 3.0.1
Dear R users,
I discovered something strange using the function agnes() of the cluster
package on R 3.0.1 and on R 2.14.1. Indeed, the clusterings obtained are
different whereas I ran exactly the same code.
I quickly looked at the source code of the function and I discovered that
there was an important change: agnes() in R 2.14.1 used a FORTRAN code
whereas agnes() in R 3.0.1 uses a C code.

Agnes Help
Hi,
I'm trying to use the cluster package and I'm having some trouble... I
always get the message:

> Error: could not find function "agnes"
the package cluster is listed in the library() command, and I can reach the
help files from Agnes as well
I know that this can be some really easy thing to fix, but right now I have

agnes not working
Hello!
I created a distances matrix for 13 objects using daisy (see the attached file).
I am trying to clusteranalyse it using agnes but it's not working.
What might be the problem:
mydistances<-read.csv("Results of daisy.csv")
mycluster<-agnes(mydistances, method="ward")
I am getting:
Error in agnes(mydistances, method = "ward") :

[LLVMdev] [LNT] Does LNT's mouse wheel zooming work well anywhere?
This is only a minor annoyance, but mouse wheel zooming on LNT graphs is pretty broken on at least OSX. It does not work correctly on Chrome, Safari or Firefox. On Safari and Chrome the zoom is way to sensitive, on Firefox, the page scrolls while mouse wheel zooming. This appears to be a limitation of the flot graphing package we use.

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)

agglomerative coefficient in agnes (cluster)
I haven't read the book, but could anyone explain more
about this parameter?
help(agnes) says that ac measures the amount of
clustering structure found. From the definition given
in help(agnes.object), however, it seems that as long
as
the dissimilarity of the merger in the final step of
the
algorithm is large enough, the ac value will be close
to
1. So what does ac really mean?
Thank

Plot zooming i.e. changing ylim according to xlim
Dear R-gurus,
I would like to zoom in a plot, e.g. I select a region on the x-axis and
then I would like the ranges on the y-axis to change accordingly.
Is it possible to do this with existing functions, or do I have to
invent some data selection before plotting?
See below a short example, where I select ylim with trial and error,
which I want to avoid.
Cheers, Henrik Andersson

Detect polyline relationship to map bounds?
I''m working on a mapstraction implementation modeled after the radius
search feature. (http://mapstraction.com/demo-radius.php)
I''d like to recognize when the user extends the radius beyond the
visible edges of the map and adjust the zoom level. I''m not seeing
how to test this when redrawing the circle. I thought maybe I wanted
to use polylineCenterAndZoom()

movie3d function in the rgl package
Dear list,
I'm using the function "movie3d" in the package "rgl" to create a .gif
animation of a 3d graphic. The program "ImageMagik" is working
properly, R packages are working, basic examples available in the
manual also working fine.
Problem Solved: when I tried to create more complex movies, i.e.
combining different views and zooming, the R-console crashed
