I want to create 8 trellis (|experiment) scatterplots with regression lines
for prey and pred in each plot with different colouring. So far i am
creating trellis plots- but the separation in these groups is never
possible.
library(lattice)
graphs<- read.table("table.txt", header=T)
attach(graphs)
names(graphs)
str(graphs)
xyplot(abund ~ bif | experiment, data=graphs, groups=stage,
panel=function(x,y){panel.xyplot(x,y, pch=16)
panel.abline(lm(y~x))})
Thanks a lot for your help!!

Yvonne,
With ggplot2 you could tackle this problem with the code below.
library(ggplot2)
graphs<- read.table("table.txt", header=T)
ggplot(data = graphs, aes(x = bif, y = abund)) + geom_point() +
geom_smooth(method = "lm") + facet_grid(. ~ experiment)
Have a look at the ggplot2 website for more info
(http://had.co.nz/ggplot2/)
HTH,
Thierry
