I'm trying to make a monthly boxplot using this:
boxplot(varmeasure ~ vardates)
vardates = [1] 10/1/2010 10/1/2010 10/1/2010 10/1/2010 10/1/2010 10/1/2010
10/1/2010
[8] 10/1/2010 10/1/2010 11/1/2010 11/1/2010 11/1/2010 11/1/2010 11/1/2010
....
varmeasure = [1] 0.0 26.0 0.2 -0.2 -1.2 -0.8 0.0 4.4 -0.6
-0.2 14.4 -0.2
[13] 4.8 4.0 2.8 3.2 3.8 3.2 -11.4 0.2 0.4 3.0 0.6 6.2
....
they have same size.
My problem is that R is ploting ordered by months and not by year and by
months
I'm getting 1/1/2011, 10/1/2010, 11/1/2010, 2/1/2011
How can I plot it in chronological order?
thanks
