Hello all,

    I have a peculiar and particular bug that I stumbled across with
ggplot2.  I cannot seem to replicate it with anything other than my specific
data set.

    Here is the problem:

   - when I try to plot a histogram, allowing for ggplot2 to decide the
   binwidths itself, I get the following error:
      - stat_bin: binwidth defaulted to range/30. Use 'binwidth = x' to
      adjust this.
      - Error: position_stack requires constant width

    My code is simply:

ggplot(data=myDataSet, aes(x=myVarOI)) + geom_histogram()

or

qplot(myDataSet$myVarOI)

    If I go ahead and set the binwidth to some value, then the plot can be
made without problems.

    The problem is with the specific data that it is trying to plot.  I
suspect it is trying to create bins of different sizes, from the error
code.  Here are the basics of my data set:

   - length:  1936 entries
   - 1906 unique entries
   - stats:
   -      Min.   1st Qu.    Median      Mean   3rd Qu.      Max.
   3.200e+09 6.312e+09 6.591e+09 6.874e+09 7.551e+09 1.083e+10



    I cannot imagine this can be solved without my specifically uploading
the actual data.  If I simply attach it, will it be received by r-help?
Hadley, if you're interested, would you like me to send you the data
directly to you?

                                          Regards,
                                                 Mike

Tacoma Narrows bridge collapse explained with abstract phase-space maps,
Some x-ray slides, a music score, Minard's Napoleanic war:
The most exciting frontier is charting what's already here."
