Plotting matrix rows with lattice graphics?
Maybe: xyplot(values ~ ind|ind, data = stack(split(m, 1:4)))

Sorry if this is an FAQ, but I haven't found the answer (yet)... I'm trying to plot each row of a simple numeric matrix in a separate panel using the layout features of lattice, but can't make it work - help would be appreciated! Example:
> m <- matrix(seq(1:20), nrow=4)
> 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 The following will plot one row in one box:
> xyplot(m[1,] ~ seq(1:5))
but this gives all rows in the same box:
> xyplot(m ~ seq(1:5))
Since there are no factors, how can I set conditioning variable to get
what I want, or is there a better way to do this?
Thanks in advance
