[R] Creating a histogram properly

[Joe Carl]

Hello all,

I'm trying to make a histogram of the data contained in my dataframe.
The summary of the data gives me exactly what I want

summary (Data)
V1     V2
first001: 3   last001: 9
first002: 3   last002: 7
first003: 2   last003: 6
(Other) :52    (Other): 27

But how do I capture the names and values in vectors so I can plot them?
