Hi all,
i'm fairly new to R and its graphing, but having unsuccessfully 'googled'
and checked this forum to find answer to my problem, i'm posting my question
here.
I'm trying to plot stacked barplot. I have simple data that looks like this:
bg ag
0.41 2.81
0.37 2.91
0.31 2.06
0.32 2.39
every row indicates a factor (1,2,3,4, see below in names.arg). Now when i
plot this using following function for stacked barplots:
plot<-barplot(t(data), main=txt, ylim=c(0,10), col=c("white", "grey90"),
ylab="Total biomass (g)", space=0.1, names.arg=c("1", "2", "3", "4"))
i get a lovely stacked graph and it color-codes with white (bg) and grey90
(ag) in each individual stacked bar. I have a total of 4 stacked bars as i
have 4 factors. Now here is the question: i would like to add density lines
across entire stacked bar or any other graphic feature to distinguish
between bars 1 and 2 as they indicate same factor and 3 and 4 that indicate
different factor. Is there any way to do that? Surely it's possible, but not
so obvious for the beginner =)
thank you very much
