Hi David, I don't think I quite understand bins - as when the graph changes from bins =100 to bins =10, I thought the x axis would change, so what exactly is being group? Thank you for the further clarification. Atty.

Hi David, everything is ok. Just this message appears... Removed 78 rows containing non-finite values (stat_bin). What is that mean?
Louise Blight • April 9, 2021
There's an informational pop-up in the exercises file (at line 63 in my code) that reads "
stat_bin()usingbins = 30. Pick better value withbinwidth". Should this readbinsinstead ofbinwidth? I tried the latter and it seems to code for the actual width of the bins - no surprise I guess - instead of the number of bins we're adjusting in this exercise.
