hi there!
i am searching for a possibility to plot the cluster fusion number against the
distance in hierarchical clustering. i used the following code:
distances = dist(my data[, c(1:11)],
method=euclidean)
eward = hclust(distances, method=ward)
plot(eward, labels=my data[, 12],
Hey there!
I am searching for an attribute evaluation algorithm (such as based on Info
gain, Gain ratio or Chi squared statistics).
Is something like that available in R?
Thanks for your reply.
Best regards,
Julia

Hallo!
Is there a package in R that does Q-type factor analysis?
I know how to do principal component analysis, but haven't found any
application of Q-type factor analysis.
Thx,

Hey there!
I got a pseudo code and don't know how to apply it to R, maybe someone can help
me:
Input: A dataset X, kmax: maximum number of clusters, num_subsamples: number of
subsamples.
Output: S(i; k) - a distribution of similarities between partitions into k
clusters of a reference
Hallo!
I would need a code for 10-fold cross validation for the classifiers Naive
Bayes and svm (e1071) package. Has there already been done something like that?
I tried to do it myself by applying the tune function first:
library(e1071)
tune.control - tune.control(random =F, nrepeat=1,
7 matches
