[R] sorting matrix to match an ordered list

[Nick Matzke]

Hi all,

This can't be very hard, but it is sticking me because I am a beginner. 
  Setup:

x = rbind(c(0,1,1), c(2,3,1), c(4,5,1))
y = as.matrix(x)
rownames(y) = c("a","b","c")
colnames(y) = c("a","b","c")
ordered_list = c("b", "c", "a")

How do I produce a new matrix, z, with the rows and columns both sorted 
in the order specified by ordered_list?

(I have a big 124x124 output matrix that comes out with the rows & 
columns in alphabetical order, I want them in a pre-specified order I 
can get from the input file, but the above is an example of the 
conceptual issue)


Thanks!

Nick
