Display dollar sign in grid.draw

How can I add a dollar symbol and round it to two digits in the table drawn by the grid.draw

package gridExtra

?

I use round

before to draw the table, but I don't know how to round and add "$" together and draw the table. Any suggestion would be appreciated.

Using plyr

, you can use a function colwise

to apply a function on many columns.

library(plyr)
dat <- numcolwise(round_any)(dat,0.01)
dat <- colwise(paste)(dat,'$')
