accessing a table

From: Greg Trafton <trafton at itd.nrl.navy.mil> Hi, all.  I'm sure
this is a simple question, but I'm having problems figuring it out
myself...  I have a table:

currenttable <- table(junk[-1],junk[-n])
currenttable
     
      bar foo junk
 bar    2   2    0
 foo    1   0    0
 junk   0   0    1

and I'd like to know the result of the cell currenttable(bar,foo).

currenttable[1,2]

or even

table(junk[-1],junk[-n])[1,2]

Whoops!  I should have been a bit more specific!  sometimes foo is not
in the table, so I do not know exactly what row or column it is in; I
need to access it via the "headings" (rows and column names).  

thanks!
greg
