[R] Changing a logical matrix into a numeric matrix

[emj83]

Hi,

I would like to turn my TRUE/FALSE matrix into a 1/0 matrix (i.e. True=1 and
False=0)

      [,1]  [,2]  [,3]  
[1,]  TRUE FALSE FALSE 
[2,]  TRUE  TRUE FALSE 
[3,]  TRUE  TRUE  TRUE 

      [,1]  [,2]  [,3]  
[1,]    1    0     0
[2,]    1    1     0
[3,]    1    1     1

Is there a quick way of doing this without a loop?

Thanks Emma
