Hello Geo-Rs!

I'm using the latest version of gstat and spacetime.  I'm trying to fit a variogramST, but I get the following:

>  city1b.st <- STFDF(sp=tempb,time=liltime,data=data.frame(index=city1b.df$index))
>
> str(city1b.st)

In addition: Warning message:

Does this look familiar, please?

Thanks for any help.
