keeping dim() for array
...he following: pip = array(1:6, dim = c(3,2)) dim(pip) [1] 3 2 pup = pip[1,] dim(pup) NULL I bet there is a *good* reason why one row of an array is *dimensionless*, but it's highly inconvenient for my purpose, i.e. to use apply() after an array goes through a number of logical steps and is redimensioned, sometimes to one single row. How do I keep dim(pup) to 1 2? Since pup is at the end of a number of if(), it does not necessarily end up as one row only, so t(as.matrix(pup)) is the *wrong* answer. Best, Federico -- Federico C.

converting matrix in array
Hi everyone, have a small problem trying to converting a dataset in matrix form to an array. Specifically: data include 3D measurement -x,y,z of 59 points in 36 objects. They are stored as a matrix (x) of 2124 rows and 3 columns. What I want to do is to extract each subject's dataset using an array (b). Accordingly, I tried the following command: b<-array(a,c(59,3,36)). The problem is

Windows startup question
...9;vcd': The following object(s) are masked from package:base : print.summary.table summary.table Error in dim(votes) <- c(10, 7, 9, 2) : cannot do complex assignments in base namespace So it seems the first 2 lines are executed, the vector votes exists, but cannot be redimensioned as an array. Can i make what I would like fully functional? -- Erich Neuwirth, Computer Supported Didactics Working Group Visit our SunSITE at http://sunsite.univie.ac.at Phone: +43-1-4277-38624 Fax: +43-1-4277-9386

Coercing elements of a matrix from integer to double
Ive been converting elements of matrices and arrays, e.g., from Integers to double-precision, by vectorizing the matrix and then remaking it. Alternatively, I can redefine one element as double which then redefines them all. Both methods are quick, so I guess I shouldn't complain, but I would have thought there'd be something more obvious. Have I missed it? Here's my redimensioning

Working with Matrix
Hello again, Let say I have 2 matrices which equal number of columns but different number of rows like: Mat1 <- matrix(1:20, 4, 5) Mat2 <- matrix(1:25, 5, 5) Now for each column 1-to-5 I need to fetch the corresponding columns of these 2 matrices and add the corresponding elements (ignoring NA values if any). Therefore for the 1st column I need to do: (1+1), (2+2),...,(4+4), (NA+5) and

How to create a matrix with 3 dimensions from several 2 dimensional matrice?
Hi every one, How is it possible to create a matrix with 3 dimensions from several 2 dimensional matrice? Is it possible that each of "elementary/building block" matrices could be called by its corresponding original name? Thanks alot. -- View this message in context:

r data structures
hi, i'm trying to understand r data structures. i see that vectors, matrix, factors and arrays have a "dimension." there seems to be no mention of dimensionality anywhere for lists or dataframes. can i consider lists and frames to be of fixed dimension 2? thanks, jay s
