image() and nonsquare matrices
How do I draw non-square matrices with image() and get the axes right?
Try 1:
a <- matrix(rnorm(100),20,5)
image(1:20,1:5,a,asp=1,xlab="label here")
# No good because the axes don't touch the image
Try 2:
image(1:20,1:5,a,asp=1,axes=F,xlab="label here")
axis(side=1,pos=0)
# No good because the x axis label is floating far from the x axis.

block diagonal matrix function
Hello List
I have just written a little function that takes two matrices as
arguments and returns a large matrix that is composed of the two input
matrices in upper-left position and lower-right position with a padding
value everywhere else. (function definition and toy example below). I
need nonsquare matrices and rowname() and colname() inherited appropriately.
Two questions:
(1) Is there a better way to do this? (kronecker() isn't applicable here)
(2) How do I generalize it to take an arbitrary number of matrices as
inputs?
