Error: memory exhausted
I'm using a pentium 133 with 32 MB ram memory!
What I must to do?
Thanks and excuse me for my english!

R-beta: Time Series Analysis
I have just downloaded rsept.zip and rseptbeta.zip for Windows 95 and I
think that is a GREAT product.
1st: I want to know the differences between them.
2nd: I'm interested very much in time series analysis, but watching the
html help there is not any function (for ex. like the S-Plus functions acf
pacf and arima functions etc). If there is some pacages to plug-in with

R-beta: generate a dll for R for win95
Hi,
I've just downloaded a fracdiff.tar.gz (package for arima(p,d,q)
modelling) I would like to plugh-in to R for windows 95 (rsept), how can
I make a "*.dll" from the fortran code to put into "lib" directory, and
a "library file" to put into "library" directory?
Please help me I'm very interested in the arima modelling.

limit of cmdscale function
Hi
We have a few questions regarding the use of the "isoMDS" function.
When we run "isoMDS" function using 60,000 x 60,000 data matrix,
we get the following error message:
------------------------------------
cmdscale(d, k) : invalid value of 'n'
Calls: isoMDS -> cmdscale

We checked the source code of "cmdscale" and

spearman rank correlation problem
Hello R gurus,
I want to calculate the Spearman rho between two ranked lists. I am
getting results with cor.test that differ in comparison to my own
spearman function:

if(length(l1) != length(l2)) stop("lists must have same length")
r1 <- rank(l1)
r2 <- rank(l2)

R-beta: executable problem
I downloaded the rseptbeta.zip and exe.zip files for Windows (I'm
running Win 95 4.00.950a) about three weeks ago and until now had
been very impressed.
Today the executable rsept.exe (dated 10/29/97) went strange. It would
open a window and immediately close the window (I've seen this
before when inadvertently trying to open certain non-windows
applications within windows). Here is

cmdscale problem
Dear R developers,
there appears to be a small problem with function cmdscale: for
non-Euclidean distance matrices, using option add=FALSE (the default),
cmdscale misses the smallest eigenvalue. This affects GOF statistic g.1
(See Mardia, Kent + Bibby (1979): Multivariate Analysis, eq. (14.4.7).
The corresponding formula in Cox + Cox (2001): Multidimensional Scaling,
2nd ed., p 38, would

cmdscale k=1
In applying multidimensional scaling, it seems to me that sometimes the
underlying dimensionality of the matrix is 1. However I found a case
where cmdscale failed when I tried k=1. Here it is:
m<-matrix(
c(.5,.81,.23,.47,.61,
.19,.5,.06,.17,.28,
.77,.94,.5,.74,.85,
.53,.83,.26,.5,.64,
.39,.72,.15,.36,.5),
nrow=5)
# BTW I think cmdscale uses only the lower triangle--how to enter only
# that

NaN values returned by cmdscale
Hello all,
I'm using R1.7.1 on Linux, generating sammon-optimized MDS plots from
distance matrices. This is a calculation I run routinely, often on
sample sets of up to 100 samples. This time, with three samples, the
sammon function returned an error (shown below), which I tracked down to
the cmdscale function it uses to find a starting configuration. In
short, cmdscale is returning NaN

Difference between prcomp and cmdscale
I'm looking for someone to explain the difference between these
procedures. The function prcomp() does principal components anaylsis,
and the function cmdscale() does classical multi-dimensional scaling
(also called principal coordinates analysis).
My confusion stems from the fact that they give very similar results:
my.d <- matrix(rnorm(50), ncol=5)
rownames(my.d) <-

cmdscale question
Hi.
I know matrices that use distances between places works fine when using
cmdscale. However, what about matricies such as:
A B C D E
A 0 1 23 12 9
B 1 0 10 12 3
C 23 10 0 23 4
D 12 12 23 0 21
E 9 3 4 21 0
i.e. matrices which do not represent physical distances between places (as
they would not make sense for real distances such as the one above)

cmdscale: labels missing (PR#1220)
The function cmdscale tries to copy names from the source to the
result. This only works if the source is a matrix.
If m is a matrix with labels (rownames) and d is an object of
class "dist" with labels, this works:
cmdscale(m)
...but with this, there are no labels in the results:
cmdscale(d)
However, this works:
cmdscale(as.matrix(d))
My suggestion is to change, in

How does clusplot exactly make use of cmdscale?
Dear people,
I used clusplot to plot a partition result. The partition result was from
pamk with a distance object as input. Then I applied cmdscale on the same
distance object for coordinates to make another scatterplot.
My problem is this: the coordinates from the cmdscale calculation, though
with the same shape, were different in scale and rotation from the scatter
plot yielded by clusplot.

Intermittant hang in cmdscale (PR#2323)
Full_Name: Cam Webb
Version: 1.6.0 (fink X11 compile)
OS: Mac OS X (Jaguar)
Submission from: (NULL) (64.168.28.87)
This is an unpredictable, intermittant hang during cmdscale of the mva library.
Some data never cause a problem, other data always do, abut I can't track down
the difference in the structure of the data. Sometimes the function will work
for `difficult' data after it has

convert dataframe to matrix for cmdscale
I have a dataframe like this (toy example):
x y z

"b" "b" 0
"b" "c" 1.3
