I'm helping colleagues with analysis of frog calls at night, and they want to plot call statistics against time. This means we hit a problem: we want the x-axis to start at (say) 18:00 and end at (say) 06:00. I'm reluctant to use the date as well, because we have data from several dates, but only want to plot against time of day.
Here's some code to illustrate the problem (don't worry about the data being outside the range of the plot: this is only for illustration). library(chron) Times <- chron(times.=paste(c(18:23,0:9),":30:00", sep="")) Thing <- rnorm(length(Times)) # just something for the y-axis plot(Times,Thing) # x-axis wrong plot(Times,Thing, xlim=chron(times.=c("05:00:00", "18:00:00"))) # x-axis right plot(Times,Thing, xlim=chron(times.=c("18:00:00", "05:00:00"))) # would like this to work... Can anyone suggest a solution?
