[R] Ploting a matrix

[baptiste auguie]

the result of read.table is a data.frame, not a matrix as you first  
suggested. Can you copy the result of str(b) so we know what your data  
is made of?

I'm guessing the most elegant solution will be to use the reshape  
package, followed by ggplot2 or lattice.
