Here is an example you can use: #Generate random normal variables to use as dummy data for Fisher's Alpha alphaBCI<-rnorm(100) #Assume you have 5 sites, each with 20 data points sites<-rep(c("Site 1", "Site 2", "Site 3", "Site 4", "Site 5"), each=20) #Making sites a factor will produce the stratified boxplots sites<-as.factor(sites) #Produce boxplot boxplot(alphaBCI~sites)

I need to plot a diversity measure (Fisher`s alpha) for different sites. I calculated the values using the following commands: Data(BCI) alphaBCI <- fisher.alpha(BCI) I need boxplots showing the data variation between sites. Then I tried: boxplot(as.data.frame(alphaBCI)) However, it does not appear the box plots for different sites but only the boxplots for alpha, se, df. Residual and code? Do anyone know the right expression? Thank you very much, Bert [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
