sure that I have used glm, stepAIC, and update correctly. Something is
strange because I get a different result between:
1) a glm of 12 predictor variables followed by a stepAIC where all
interactions are consi
Hopefully this is a pretty simple question:
Is there a function in R that calculates the "mode" of a sample? That is, I
would like to be able to determine the value that occurs the most frequently in
a data set.
I tried the default R "mode" function, but it appears to provide a storage typ
Thanks! Works like a charm.

Generally, how to scale different variables when aggregating them in a
dissimilarity measure is strongly dependent on the subject matter, what the
aim of clustering and your "cluster comncept" is. This cannot be answered
properly on such a mailing list.

Hello R experts!
Last week I run in to a lot a problems triyng to fit an ARIMA model to a

I am going to try out a tentative clustering of some feature vectors.
The range of values spanned by the three items making up the features vector is
quite different:
Item-1 goes roughly from 70 to 525 (integer numbers only)
Item-2 is in-between 0 and 1 (all real numbers between 0 and 1)
Item-3 g
oops, that really was easy:
(wtd.table(FamTyp.kurz,HGEW,normwt=FALSE,na.rm=TRUE)) instead of
(wtd.table(FamTyp.kurz,weigths=HGEW,normwt=FALSE,na.rm=TRUE))
sorry for that question ...

Hi there,
I'd like to create a heatmap from my matrix with
a) a defined color range (lets say from yellow to red)
b) using striking colors above and below a certain threshold (above = "green",
below = "blue")
Example matrix (there should be a few outliers generated...) + simple levelplot

Hi useRs & developeRs,
I got stuck within a function of the Hmisc package. Sounds easy, hope it is:
I got 2 items (FamTyp.kurz, HGEW) of same length, no missings.

Hello.
How can I analyse the cross-correlation between two time series with ccf, if
one of the time series need to be differenced, so it is stationary?
The two time series differ when in length and maybe ccf produces not the
correct cross-correlation?!
Another problem:
How can I model the two t

Version 4.06 of the caret package was sent to CRAN.
caret can be used to tune the parameters of predictive models using
resampling, estimate variable importance and visualize the results.
There are also various modeling and "helper" functions that can be
useful for training models. caret has wrapp
