the dataset I am using (data.it) is organized as follows ... ... ... ... and plotting it using dotplot, I specified the script as:
library(lattice)
attach(data.ita)
dotplot(reg~stp | partner, data=data.ita, groups=btp,
xlab=list("Data - it",cex=1.5),col=c("black","red"),aspect=0.3,as.table=TRUE,xlim=c(-1,1))
detach(data.ita)
In the resulting plot the variable "reg" is ordered alphabetically. Instead, I would like the variable to be plotted in the following order: "s", "s-f", "d", "d-f".
Make that an ordered factor as follows:
data.it$reg <- ordered(data.it$reg, levels=c("s", "s-f", "d", "d-f"))
hope this helps,
