Dear list,
I am struggling with the spplot function, in detail, a) labeling some
contours superimposed on a grid. How can I control the contour's font
size? b) How can I set values above 0.6 transparent?
I played around using panel utility functions for spplot but got no
appropriate solution.
# example
library(sp)
data(meuse.grid)
gridded(meuse.grid) = ~x+y
densplot <- spplot(meuse.grid, c("dist"),
col.regions=rev(gray.colors(20)), contour=T, labels=T, pretty=T,
panel = function(...) {
panel.gridplot(...)
#sp.lines(...)
})
print(densplot)
I appreciate every hint!
Best regards
Marco
