order in stacked barplot
Posting guide warns you to provide a reproducible example, which would include enough data to test code.
As a general point of information I can say that data ordering in R graphs is normally driven by the factor level ordering, and you usually have to specify that explicitly when you convert from character to factor.

Hello
i did a stacked barplot using ggplot and R arranged the bars of the
items in
different orders. i don?t know why. but i want to have the same order
in
every stacked bar.
I used the code
data1 <- read.table("N_O_W_MAI.txt", header=TRUE, dec = ",")
attach(data1)
Teich1<-factor(Teich,levels=c(5,7,9,11,"G") ,ordered=is.ordered(Teich))
Gruppe1<-factor(Gruppe,levels=c("Annelida","Cladocera","Copepoda",
"Diptera","Ephemeroptera","Ostracoda","Sonstige"),ordered=is.ordered(Gruppe))
data2<-data.frame(Teich1,Gruppe,Herkunft,IRI)
data2
str(data2)
'data.frame': 65 obs. of 3 variables:
$ Teich1: Factor w/ 5 levels "2","4","8","10",..: 1 1 1 1 1 1 1 1 1 1
...
$ Gruppe1: Factor w/ 7 levels "Annelida","Asellus",..: 1 2 3 4 5 6 7 1
2 3
...
$ IRI : num 0.606 16.274 0.326 0.396 0 ...
attach(data2)
#?data.frame
str(data2)
library(ggplot2)
ggplot(data2, aes(Teich1,IRI, fill=Gruppe1)) +
geom_bar(stat="summary", fun.y="sum") +
facet_grid(~Herkunft)
So i get a plot with stacked bars for every "Teich1"(Pond), the stacks
show
the summed proportion ("IRI") of the diffrent species ("Gruppe1") in
every
pond. Every species has a discret colour, but the order of species is
displayed different for the ponds. In the original data they have the
same
order for every pond. This is what i want to have for the stacked
barplot,
too.
Has anybody an idea?
thanks
Kay
