R help - Mar 2016 - Warning message: Computation failed in `stat_bin()`: attempt to apply non-function

Hi,

I am trying to plot a sample dataset using ggplot2, but I am keep getting
the following error message and an empty plot!
Apparently something is wrong in the dataset, but what?

R :
pf<-read.csv('pseudo_facebook.tsv', sep='\t')

ggplot(x=aes(friend_count), data=pf) + geom_histogram()

stat_bin()` using `bins = 30`. Pick better value with `binwidth`.
Warning message:
Computation failed in `stat_bin()`:
attempt to apply non-function

The dataset can be found at :
https://s3.amazonaws.com/udacity-hosted-downloads/ud651/pseudo_facebook.tsv

thanks,
/Shahab

> ggplot(x=aes(friend_count), data=pf) + geom_histogram()
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.
