[R-sig-eco] R graphics cookbook
Hi everyone, I am trying to apply the following lines of coding (they are from the R Graphics Cookbook, Chapter 3: Bar Graphs): ggplot(data, aes(x=year_bis,y=area)) + geom_bar(stat=identity) I do have a data.frame as follow: id year start_day locarea 1 1 2010 155 20 3.4388 2 1 2010 169 18 11.6576 3 1 2010 183 17 15.5893 4 1 201071 41 22.0356 5 1 2010 127 42 27.2602 6 1 201099 37 52.2779 str(data)'data.frame':221 obs. of 5 variables: $ id : int 1 1 1 1 1 1 1 1 1 1 ... $ year : int 2010 2010 2010 2010 2010 2010 2008 2010 2009 2010 ... $ start_day: int 155 169 183 71 127 99 337 1 337 113 ... $ loc : int 20 18 17 41 42 37 10 36 41 40 ... $ area : num 3.44 11.66 15.59 22.04 27.26 ... I called both packages gcookbook and ggplot2 (among others). That's a rather easy line of coding, but for some reasons I do have the following warning message: Error in as.environment(x) : incorrect objet for 'as.environment' Do you have any clue why? Thanks a lot. Greetings. -- Dylann Kersusan Master Biodiversity and Conservation Zoology dept. Stockholm University -- Grimsö Wildlife Research Center Ecology dept.

Re: [R-sig-eco] R graphics cookbook
I see `area` in your data.frame, but where's `year_bis`?

Hello, you've probably already figured it out, but the error is because you are telling ggplot to use an x variable which doesn't exist: ggplot(data, aes(x=year_bis,y=area)) + geom_bar(stat=identity year_bis is not a column in the data frame you show us, if you change it to: ggplot(data, aes(x=year,y=area)) + geom_bar(stat=identity) it should work.
