Not at all!

## a *vector* of 100 million observation
x <- rnorm(10^8)
## a histogram for it (see attached for the result from my system)
hist(x)

No data frame required.  I would not try this straight in anything but
traditional graphics for a 100 million observation vector, but if you
wanted it made in ggplot2 or something, you could prebin the data and
THEN plot bars corresponding to the bins.

Cheers,

Josh
