[R] montly mean temp plot

[Greg Snow]

Without a reproducible example (we don't have month and X1999) it is hard to tell for sure, but my guess is that month is an (unordered) factor without the ordering specified, so it defaults to alphabetic.  Change it to a factor with the months properly ordered and the plot should match what you want.  One possible way to do this is:

> month <- factor(month, levels=month.name)

Or

> month <- factor(month, levels=month.abb)

Or if those don't work, then you will need to provide a set of months in the correct order that match with your data.

If that does not help, then send us more info on your month variable (str(month)), or better, a full reproducible example.
