Hi all
I hope you might help me with some aspects of producing a graph in lattice. There are three things I have struggling with and that is: 1. to separate the horizontal box rows from each other; 2. to change the colour of the horizontal and vertical strips to white; and 3. to place the axes labels on the left y axes and on the bottom x axes. I would really appreciate some help. I have put the following example together. I tried "between=list(y=c(1))" to try and separate the horizontal box rows but perhaps I have not used this correctly. I tried to use the following to place the labels on the left y axes "scales=list(y=list(alternating=c(1))" but again perhaps I didn't use this correctly.
library(lattice)
library(latticeExtra)
n=as.factor(c(1:5,1:5))
Breed=as.factor(c(rep("Cow",3),rep("Sheep",3),rep("Goat",2),rep("Yak",2)))
Test=as.factor(c(rep("Bovine viral diarrhoea",5),rep("Border Disease",5)))
Titer=as.numeric(c(10,20,30,40, 50,15, 25, 35, 45, 55))
heif=data.frame(n,Breed, Test, Titer)
x=barchart( heif[,4]~ heif[,1]| heif[,3]+ heif[,2] ,ylab="titer",
layout = c(2,2), scales=list(x=list(at=c(seq(0, 60, by = 15)),tick.number=c(5),
labels=c(seq(0, 60, by = 15))))
)
useOuterStrips(x)
