Warning message: Computation failed in `stat_bin()`: attempt to apply non-function
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. John Kane Kingston ON Canada

Subject: [R] 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,
