Dear all,
I'm trying to rearrange variables in a table in a custum order for using it
with levelplot. So far I could only find examples showing how to sort
alphabetically. Here is a short example:
a<- c("Anna","Anna","Michael","Klaus","Klaus","Anna","Fritz")
b<- c("Schnitzel","Pommes","Pommes","Schnitzel","Wurst","Schnitzel","Schnitzel")
food<- matrix(c(a,b),7)
as.data.frame(food) -> tmp
as.data.frame(table(tmp)) -> X
levelplot(X$Freq ~ X$V1 * X$V2,xlab="people",ylab="food")
Food is now ordered: Pommes, Schnitzel, Wurst.
But I need: Schnitzel, Pommes, Wurst.
How can I define the order? I'm happy about every suggestion.
The general answer to that question is to make b into a factor with the
levels in a specified order, e.g. by
b <- factor(b, levels=c("Schnitzel", "Pommes", "Wurst"))
However, this doesn't survive the other strange things you are doing.
If you simplify the rest, it should be fine. For example:
food <- data.frame(a,b)
X <- as.data.frame(table(food))
levelplot(Freq ~ a * b, data= X)
