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

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.

Could be few things but we probably need some sample data to get a feeling for what you are doing. The easiest way to supply data is to use the dput() function. Example with your file named "testfile": dput(testfile) Then copy the output and paste into your email. For large data sets, you can just supply a representative sample. Usually, dput(head(testfile, 100)) will be sufficient.
