Buenos dias, desde hace algunos dias estoy realizando un trabajo,mi computadora es una DELL, windows 10 64 bits, 8G de RAM y disco de estado solido, estoy procesando 29000 filas y 23 columnas, mi codigo es este:
nb <- NbClust(datos.scaled, distance = "euclidean", min.nc = 2,
#max.nc = 10, method = "complete", index ="all")
.
y mi error es este:

self defined distance matrix in NbClust
i m using a package NbClust for cluster analysis. in the following algorithm
->NbClust(m, diss="NULL", distance = "euclidean", min.nc=2, max.nc=15, method = "ward", index = "all", alphaBeale = 0.1)
i want to define my own dissimilarity matrix of dimension 38*38. my original data "m" is a matrix of 365*38. whenever i define my own dissimilarity

choosing the correct number of clusters usinf NbClust
I am attempting to use NbClust to examine different indices to determine
the number of clusters. The code appears to be working and I am getting
results. However, I have noticed that each time I run it I may get
different answers. For example looking at the DB index one run
recommended 6 clusters while the next 5 - the code is exactly the same.
I assume there is some randomization that I

choosing the correct number of clusters using NbClust
I have the same problem you mention here. As there is no answer, did you
find the way to obtain the optimal number of groups? Thank you!

IF STATEMENTS
Hello,
I am working on using if statements. What is the error message telling
me here and how do I correct for it?
I have tried various combinations of quotes.
Thank you.

Error in if (is.na(n) || n > 65536L) stop("size cannot be NA nor exceed 65536") : missing value where TRUE/FALSE needed
Dear useRs,
i am using NbClust to determine appropriate number of cluster for hclustering. i am consistently getting the following error
Error in if (is.na(n) || n > 65536L) stop("size cannot be NA nor exceed 65536") :
missing value where TRUE/FALSE needed
Does any one know where i am wrong??
thanks in advance

Would like to add this to example for plotmath. Can you help?
Greetings:
I would like comments on this example and after fixing it up, I need
help from someone who has access to insert this in R's help page for
plotmath.
I uploaded a drawing
http://pj.freefaculty.org/R/Normal-2009.pdf
that is created by the following code
http://pj.freefaculty.org/R/Normal1_2009_plotmathExample.R
This will be a good addition to the plotmath help page/example.

R algorithm for maximum curvatures measures of nonlinear models
Hi all,
I'm looking for the algorithm to calculate maximum intrinsic and parameter effects curvature of Bates & Watts (1980). I have Bates & Watts (1980) original article, Bates et al (1983) article, Seber & Wild (1989) and Ratkowsky (1983) books. Those sources show steps and algorithm to get this measures but I don't know translate C code to R language and I've no success

custom loss function + nonlinear models
Hi all;
I'm trying to fit a reparameterization of the
assymptotic regression model as that shown in
Ratkowsky (1990) page 96.
Y~y1+(((y2-y1)*(1-((y2-y3)/(y3-y1))^(2*(X-x1)/(x2-x1))))/(1-((y2-y3)/(y3-y1))^2))
where y1,y2,y3 are expected-values for X=x1, X=x2, and
X=average(x1,x2), respectively.
I tried first with Statistica v7 by LS and
Gauss-Newton algorithm without success (no
