It worked, thanks.
Is there a way to put a trend line through the boxplots?
You have not shown us how you set the data up or made the boxplots. A
"trend line through boxplots" seems be a bit ambiguous, since the x-
variable needs to be a factor and a factor variable would not
necessarily have either a scale or an order. So the answer with the
available information cannot be anymore specific than "it depends".

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?
By converting those character strings to dates. At the moment you
seem to
believe that R has the ability to "know" that you want these
strings to be
dates.
?as.Date
