How can I draw a boxplot of an R table?

I have a table produced by calling table(...) on a column of data, and I get a table that looks like:

0   1   2   3   4   5   6   7   8   9   10  11  12  13  14  15  16  17  18  19 
346 351 341 333 345 415 421 425 429 437 436 469 379 424 387 419 392 396 381 421

I'd like to draw a boxplot of these frequencies, but calling boxplot on the table results in an error:

Error in Axis.table(x = c(333, 368.5, 409.5, 427, 469), side = 2) : 
   only for 1-D table

I've tried coercing the table to an array with as.array but it seems to make no difference. What am I doing wrong?

If I understand you correctly, boxplot(c(tab)) or boxplot(as.vector(tab)) should work (credit to @joran as well).
