[GRASS-stats] difference in loading different grass layers in one object compared to separate objects?

[Rainer M Krug]

Hi

is there a performance difference in loading several grass raster
layers into one SpatialPixelsDataFrame compared to separate?

I am asking because I have to load several layers in a simulation
repeatedly and a performance difference might show.

Also:

what is the best way of accessing the associated data in these objects? I use

spsdf[[1]], sp[[2]], ...

is that OK, or is there a preferred way?

Thanks

Rainer
