[R] Transposing the output of 'table'

If you want a dataframe rather than a matrix, I often use the as.data.frame method for table objects.  See ?table for the documentation.  You can even nicely name the dimensions and frequency.

OBJECT <- sample(4, 20, TRUE)

as.data.frame(table(var1 = OBJECT), responseName = 'frequency')

R 3.0.1


If I execute the command:
the output might look like:
  1   2 
 25 336 

I would like it to appear as:
	1	25
	2	336

I can accomplish this with:
	TABLE	<- table(OBJECT)
	data.frame(names(TABLE), as.numeric(TABLE))

However, I bet that a more clever approach exists?  Any takers?
