More beginner friendly ggplot code

[nkrumm]

Currently we have chunks such as:

g <-  ggplot(data, aes(x=method_a))
g <- g + geom_histogram(bins=50)
g

This is confusing (even to me) as the aesthetic should really be part of the geom_histogram. (I first realized this looking over Stephan's slides (03-exploring-data.pdf).

I would propose this re-write:

g <-  ggplot(data=data)
g <- g + geom_histogram(bins=50, aes(x=method_a))
g

Revised format: ggplot(data = data) + geom_histogram(mapping = aes(x = variable1))
