[R-sig-Geo] MultiBuffer, Intersect and Dissolve Tool in R?

[Breitbach, Nils]

Dear Community,

I am looking for a R-function (or if there is none directly in R in GRASS or QGIS) that works just like the MulitBuffer Tool from the Toolbox in ESRIs ArcGIS. Furthermore I would like to use an equivalent to the ArcGIS Tools Intersect and Dissolve. Since I am just starting to do geographical analyses with R I just do not know where to look for equivalent functions in R (Grass or QGIS).

Cheers,

Nils
