[R] Multiple R linear models into one Latex table

[Matevž Pavlič]

Hi, thanks for the help. 

Class says as follows :

> class(DF)
[1] "SpatialPointsDataFrame"
attr(,"package")
[1] "sp"
> class(grd)
[1] "SpatialPixels"
attr(,"package")
[1] "sp

Anyway, the problem was, as Rmh suggested, with the zerodist().

Tnx, m

please look at the latex() function in package "Hmisc".
