I assume you mean two line colors, not types.
Like this?
xyplot(X ~ date, groups = interaction(name,G), data = mydf.long,
type = c("l", "g"), col.line =
c("blue","red"))
Cheers,
Bert

one more change. The line type (lty) should be the same for long and short.
The line type should only change according to ?name? group. So the the graph
will have two line types (not four as in your solution).
