[R] a class matrix with class ordered data

2005-07-27 Thread Werner Bier

Deart R-help,

I could not transfer ordered data into a matrix, does anybody knows if there is 
something wrong in the code below please?

Thanks in advance, Tom

Y - ordered( unlist( Q[,1:2] ) )

z - matrix(0, nrow(Q), 2)

z - Y

is.ordered(z)

[1] T

is.matrix(z)

[1] F

i.e. Is it possibile somehow to have is.matrix(z) equal TRUE?

 Y - ordered( unlist( Q[,1:2] ) )

  This creates Y as an ordered factor.
 
 z - matrix(0, nrow(Q), 2)
 
 z - Y
 
  This completely discards the matrix z and replaces it with Y. 
Nothing of the matrix remains (except in your memory).

 is.ordered(z)
 
 [1] T
 
 is.matrix(z)
 
 [1] F

  Rather than asking only for an explanation of some little thing that 
didn't solve your problem, may I suggest you tell us more about the 
problem you are actually trying to solve.  Why are you doing this?  What 
specifically do you want to accomplish -- but expressed in terms of a 
very simple example with a few lines of code that a reader can copy into 
R on their computer and get something, then try a couple of 
modifications that might be closer to what you want.
