The x= in the above statement is wrong
ggplot(aes(friend_count), data=pf) + geom_histogram()
will work but it looks funny.
The more common way to write the command would likely be:
ggplot(pf, aes(friend_count)) + geom_histogram()
The tat_bin() message is just a warning.
Your data set has ~ 99,000 rows of data and geom_histogram() 's default is 30
bins which is probably too few to for you to see what is happening. Come to
Change the default binwidth to something a bit more manageable or perhaps use
geom_density() to look at the distribution.
