[R] format a matrix as fractions?

[Michael Friendly]

Is there some way to format a matrix of fractions as fractions?  I think 
I've seen this somewhere,
but search on Rseek came up empty.

Example:

 > outer(1/seq(1:3), 1/seq(1:3))
           [,1]      [,2]      [,3]
[1,] 1.0000000 0.5000000 0.3333333
[2,] 0.5000000 0.2500000 0.1666667
[3,] 0.3333333 0.1666667 0.1111111
 >

should print as

       1     1/2     1/3
     1/2    1/4     1/6
     1/3    1/6     1/9

TIA
-Michael
