[R] Questions about ggplot2

Hi I have two questions about using ggplot2.

First, I have multiple columns of data that I would like to combine into 
one histogram where each column of data would correspond to one bar in 
the histogram. Each column has 0 or 1s and I want my bars in the 
histogram to correspond to the sum of the 1s in each column. Does that 
make sense?

Second, is there a way to completely turn off the legend?
