Re: [R] Months in alphabetical order rather than chronological order in graph
Kurt You need to give us more information if you want good advice. For example, what sort of plot are you trying to make? A barplot? A time series? A reproducible example is always best. Please see the R-news posting guide for hints on a successful query.

Re: [R] Months in alphabetical order rather than chronological order in graph
You need to make your variable into a factor and specify the order. mymonths - c(December, March) factor(mymonths) [1] December March Levels: December March factor(mymonths, levels=month.name) [1] December March 12 Levels: January February March April May June July August September October ... December month.name [1] January February March April May June July [8] AugustSeptember October November December month.abb [1] Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec On Fri, Jan 28, 2011 at 4:53 PM, kurt_h...@nps.gov wrote: Greetings Though I have months in chronological order in my data table, the data were sampled every other month (i.e., February, April, June, August, October, December), every time I try to plot them (on the x-axis) they are plotted in alphabetical order.

Re: [R] Months in alphabetical order rather than chronological order in graph
This would be easier if you showed us a sample of your data and what commands you are using. Without we need to guess. Probably your month variable is being turned into a factor somewhere and the default for factors is alphabetical. The best solution depends on how/where/when your months are being factorized. You need to control the factorizing, maybe turning them into some type of date object instead of a factor, or create the factor, but specify the order that you want. -- Gregory (Greg) L.
