How to identify data structure?
data(AirPassengers) brings AirPassengers into the workspace. How can I idenfity what the structure of AirPassengers is? Is it a data.frame, a table etc. etc.

parsing strings between [ ] in columns
...ch
group with different sequential string.
On the example above I would like to have:
A B
1 [1, 0, 0] [0, 1]
2 [1, 1, 0] [0, 1]
3 [1, 0, 0] [1, 1]
4 [0, 0, 1] [0, 1]
Although here I have only two groups, my
real dataset will have much more (~30).
After identify the groups I would like
to idenfity the subgroups:
A1 A2 A3 B1 B2
1 1 0 0 0 1
2 1 1 0 0 1
3 1 0 0 1 1
4 0 0 1 0 1
Any hint are welcome.

probelem of function inside function
Hi,
I encountered a problem when I am trying to write my
own function which contains another function. To
simplify a problem, I tried the following simplified
function, hope someone can idenfity the problem for
me.
I have a simple data frame called "testdata" as
following:
>
testdata<-data.frame(cbind(x=c(129,109,52,118,217,278,606,198,99,133),y=c(89,118,99,137,34,14,130,30,131,30)))
> testdata
x y
1 129 89
2 109 118
3 52 99
4 118 137
5 217 34

Clustering with 'agnes'
...ters consist of points around the three main points. I was wondering if there was any way in which I can have R give me the actual cluster points at three (or any number, for that matter) clusters, ie (0,0), (0,1) and (1,0). A visual display of the clusters would be even better.
I have tried using idenfity after converting the agnes object to an hclust object, but that only gives me a listing of the points in each cluster.
I hope this question is clear. I am a little new with both clustering and using R for clustering, so please ask me to clarify if anything is unclear.
Your help would be most a...
