Thanks; for your case, with current spacetime, stplot(ciotat.t, panel=function(x,y,...) { panel.xyplot(x,y,...) sp.lines(contour) } ) might do what you need; I'll look into having sp.layout work the same way as it does in spplot, for stplot'ing STIDF objects. Best wishes, On 08/25/2011 0

Hi Edzer, Thanks for your answer. stplot(ciotat.t) gives a good result: http://www.imagup.com/data/1128936911.html It represents evolution of urbanization along time, each point being the date and location of the first building for the city "La Ciotat". The object is irregular because each spa

Hi Mathieu, the idea behind stplot is indeed that it should be as easy as spplot, hence its name. This idea is however much easier than practice, as the number of possible (and useful) plots for S/T data might be quite large. I would be helpful if you could provide (or generate) a simple data set

Hi, I have a STIDF points object named ciotat.t that I've tried to plot with a city contour named contour. I tried this but it doesn't work: > stplot(ciotat.t, sp.layout= list("sp.lines", contour)) Also, this doesn't work: > stplot(ciotat.t, panel=function(...) { sp.lines(contour) panel.p
