I'm following along on the rnaseqGene tutorial using the fission package, and I was wondering why the x axis on the time course experiment in section 9 is categorical (that is, time 1-6) rather than in minutes.
I suppose it doesn't really make a difference, however, i think it does make the graph look like the time points were evenly spaced, which is not the case.
Is there a way to display it with the actual minutes? I tried converting the minutes to numbers:
fiss$minute <- as.character(as.numeric(fiss$minute)) ggplot(fiss, + aes(x = minute, y = count, color = strain, group = strain)) + + geom_point()
But this doesn't really work, the times are still treated as discrete categories.
