Yes, that works:

class(stMeuse)

[1] "STFDF"
attr(,"package")
[1] "spacetime"

dim(stMeuse)

    space      time variables
       10         2         4

I could see that a STFDF object was created, but I still have some concern
with regard to the "id" which need to be attached to the data.frame .

With regards to my example, I tried as well with reverse-order IDs:

ds <- cbind(ds, time=sort(rep(dts,10)), id=nrow(ds):1)

...or with duplicated IDs like:

ds <- cbind(ds, time=sort(rep(dts,10)), id=rep(1:10,2))

and the final stMeuse object still seemed the same by looking at
stplot(stMeuse).
I guess they are not bound to the locations of the spatial object (points
in `meuse` in this case).

(also note that with the CRAN version of spacetime, you'd need to load

package zoo first in order to run your script)

Got it, thanks ;)
