Thanks Henrique - that didn't exactly solve my problem but gave me enough to
do so!
In your solution each row is plotted as a vertical row of points at the
value of 'ind' while I wanted to plot the values against the column numbers,
i.e. 1 to 5.
The solution was to create a vector of column numbers, replicate it and plot
against it, still using 'ind' as the conditioning variable:
> m <- matrix(1:20, c(4,5))
> m
[,1] [,2] [,3] [,4] [,5]
[1,] 1 5 9 13 17
[2,] 2 6 10 14 18
[3,] 3 7 11 15 19
[4,] 4 8 12 16 20
> pr <- rep(c(1,2,3,4,5), 4)
> d <- cbind(pr=pr, stack(split(m, 1:4)))
> xyplot(pr ~ values|ind, data=d)
Thanks again for the help
