while, but hours sounds a bit excessive).

do you mean n choose k which is a built in function see

hi, all,
how to decide the number of cluster before you use kmeans and hclust?
thank you in advance!
Depends on your criterion. Best idea is always to use the brain and
think about how many clusters are sensible for the particular
task/problem/data.
For hclust,
C function name not in load table means that youe DLL/SO file is not loaded.
You should use
.First.lib - function(lib, pkg)
{
library.dynam(your_pkg_name, pkg, lib)
}

In English we usually read this as N choose r and with that clue you might
go ?choose
Incidentally your English is fine although I see the logic in
Hello, I'm new in R and I want to do one thing that is very easy in excel,

Suppose we have the data frame:

I need to obtain another column in the same data frame (lets say
B=c(b1,b2,b3,b4,b5) in the following way:

Well, if you've deadened your brain by using Excel,
no wonder.

The suggestions by Uwe and Rolf use some of the subtler features of

Emma,
I am not an expert, but I have been trying to fit similar models.
Adding to Keith's reply to your question, I can suggest what I concluded was
the most reasonable model for my case. Based on Keith's Model1, you might
also want to allow for a correlation among years within each
hi everyone,
I'm still a newbie in statistics,
I have a question about beta distribution, that is,
On the ref/tutorials I've found on the net, why beta distribution always
have value p(x) more than 1?
As I know, any probability density function always have value not more
than 1?
is there any
A probability density must integrate to 1. The specific values of the density
can be either more or less than 1.
