R help - Feb 2010 - ggplot2/qplot question regarding reducing the no. of x-axis labels

Hi Thomas,

Please provide a reproducible example.  The most likely explanation is
that after loading your data you haven't converted your "date"
variable from a factor into a real date.

All:

I am using the command: qplot(date,MAE,data=data,facets=INTERVAL~type) 
which works fine except that the dates for my date axes are crunched 
together so much that they are unreadable. I can not find an option that 
I can set that will automatically reduce the x-axis labels to fit the 
available space.

regards to all?
