Dear R users,
x-values (EI) = Adw, EG1, LA1, Ad1, LA2, LA3...(14 levels, insect
stages)
y-valus = antpop
within the boxplot function x-values are ordered alphabetically
Idea: x-values ranked by list order (insect stage: Egg stage 1 is
followed by Larvae 1 and not by Egg stage 2 as it would be in an
alphabetically order)
Problems with the order(tapply()) function: variable lengths differ
thanks
Sibylle
R-code (as later insect stages have higher means, ordering was based
on mean or median...)
SOPRA<-read.table("SOPRA206_WG_WAE.txt", na.strings="0", header=TRUE)
ordered<-order(tapply(SOPRA$antpop, SOPRA$EI, mean))
boxplot(antpop~ordered, data=SOPRA, boxwex=0.20, at=1:14-0.2,
scales=list(x=list(rot=45)), notch=TRUE, xlab = "EVENT", ylab = "DOY",
ylim = c(100,350), yaxs ="i", col="red", subset=(wg == "ctrl"))
boxplot(antpop~ereignis, data=SOPRA, add=TRUE, boxwex=0.20,
at=1:14+0.2, xaxt="n", notch=TRUE, col="blue", subset=(wg == "scen"))
legend(1,330, c("SOPRA206 WGctrl", "SOPRA206 WGscen"), fill=c("red",
"blue"), bty="n")
text(1,340, "Waedenswil", font=2, pos=4)
