Hi,
I am using function spplot (library sp) to plot polygons:
spplot(SPDF, "var", col.regions=topo.colors(100))
SPDF is a SpatialPolygonsDataFrame
Some of my polygons are very small and you can not see the color of the
polygon (only the black borderlines).
I could use
spplot(as(SPDF, "SpatialLinesDataFrame"), "variable1",
col.regions=topo.colors(100))
to get colored borderlines.
Is there a possibility to get filled colored polygons with borderlines
in the same color?
Although it isn't obvious, you use the col= argument passed through to
grid.polygon() used internally - see ?gpar after loading the gris package.
You'll find that col="transparent" is OK:
library(rgdal)
scot_BNG <- readOGR(system.file("vectors", package = "rgdal")[1],
"scot_BNG")
spplot(scot_BNG, "SMR")
spplot(scot_BNG, "SMR", col="transparent")
Hope this helps,
Roger
Thank you for your help.
Best wishes,
Ingo
