Formatting dates on X axis in ggplot2

Question

I m having a very  very tough time getting the x-axis to look correct for my graphs     Here is my data  generated via dput      df  lt - structure list Month   structure 1 12   Label   c  2011-07-31    2011-08-31    2011-09-30    2011-10-31    2011-11-30    2011-12-31    2012-01-31    2012-02-29    2012-03-31    2012-04-30    2012-05-31    2012-06-30    class    factor    AvgVisits   c 6 98655104580674 7 66045407330464  7 69761337479304  7 54387561322994  7 24483848458728  6 32001400498928  6 66794871794872  7 207780853854  7 60281201431308  6 70113837397123  6 57634103019538  6 75321935568936     Names   c  Month   AvgVisits    row names   c NA  -12L   class    data frame     Here is the chart I am trying to graph    ggplot df  aes x   Month  y   AvgVisits        geom bar       theme bw       labs x    Month   y    Average Visits per User     That chart works fine - but  if I want to adjust the formatting of the date  I believe I should add this  scale x date labels   date format   m- Y     I m trying to make it so the date labels are  MMM-YYYY   ggplot df  aes x   Month  y   AvgVisits        geom bar       theme bw       labs x    Month   y    Average Visits per User       scale x date labels   date format   m- Y      When I plot that  I continue to get this error   stat bin  binwidth defaulted to range 30  Use  binwidth   x  to adjust this   Despite hours of research on formatting of geom line and geom bar  I can t fix it   Can anyone explain what I m doing wrong    Edit  As a follow-up thought  Can you use date as a factor  or should you use as Date on a date column

To show months as Jan 2017 Feb 2017 etc   scale x date date breaks    1 month   date labels      b  Y      Angle the dates if they take up too much space   theme axis text x element text angle 60  hjust 1

Can you use date as a factor     Yes  but you probably shouldn t         or should you use as Date on a date column    Yes   Which leads us to this   library scales  df Month  lt - as Date df Month  ggplot df  aes x   Month  y   AvgVisits        geom bar stat    identity       theme bw       labs x    Month   y    Average Visits per User       scale x date labels   date format   m- Y        in which I ve added stat    identity  to your geom bar call   In addition  the message about the binwidth wasn t an error  An error will actually say  Error  in it  and similarly a warning will always say  Warning  in it  Otherwise it s just a message
