Dear list,
I try to produce a map by sp.plot showing runoff forecasts along a river
network. Additionally to the river network (lines), I want to plot a coast
line (lines) and lakes (polygons) by using the sp.layout command. The
drawing order should be the following: 1. rivers, 2. coast line, 3. lakes.
To avoid the pre-defined drawing order of sp.plot, i used first = FALSE
within the sp.layout command as it was suggested once earlier in this forum.
But no matter where i place first = FLASE, the drawing order do not change.
This is the plotting command i use:
spplot(rivers, "Q_forecast", col.regions=col.key,
sp.layout=list(list("sp.lines","coast"),
list("sp.polygons","lakes",col="lightblue",fill="lightblue"), first=FALSE),
xlim=c(-77506.04,318494), ylim=c(6429304,6900000)
Does anyone see whats wrong or have a alternative suggestion to solve this
problem?
Thanks in advance!
Klaus
