hi,
i'm trying to figure out if there's any possibility to write a whole vector
into a matrix or data.frame or something like that. i don't mean
transormation. Here an example:
[,1] [,2]
[1,] a d
[2,] b e
[3,] c f
where e.g. a is a-c(0,1) vector of length 2, b a vector of length 4,...
It is possible to put dimensionality on a list (i.e., a generic
vector), which might be what you're looking for.
x - list(1:4, letters[1:4], function(x,y) x + y, rnorm(50))
dim(x) - c(2,2)
x[[1,2]]
x[[2,2]]
x[[3,2]] # Error
Best,
Michael

well thank you, i think we get closer to my problem. but i meant it in a
different way. maybe i describe what i intended to do:
i have number of triangles which i'd like to store in a list, matrix,...etc.
i thought it could look sth. like that:
trianglenode1node2
NA ...
z2-as.matrix(z)

You have failed to provide a complete, coherent description of what you
wish to do. In the absence of such a description, all suggestions are just
guesses. You need to think carefully about what information you want to
associate with each triangle and the appropriate data structure to use to
do
To second Bert Gunter: you may get better answers if you give us a complete
description.

Hi Thomas,
This is non trivial to do, but if you will be working with this sort
of data and are inclined to do some programming, you might consider
creating a new class. S4 classes and methods are quite flexible, and
you can allow them to lean on or inherit from existing classes such as
8 matches
