[R-sig-Geo] merge Shape file

[Joseph Bechara]

Thanks Roman, 

 

I know the rgeos package but I’m not able to identify which tools can replace the merge of ArcGIS.

I think you want the `rgeos` package that offers a plethora of functions to work with "features".

 

Cheers,

Roman

Dear Bary, 

 

Actually I have to do a geometrical merge operation.

I’m looking for the equivalent of “merge” in ArcGIS.

I’m looking for a function to merge 2 shapefiles keeping them as “spatialPolygonsDataframe” class.

Any clue?

 

 

 

What do you mean by merge? If the two shapefiles have the same set of attributes then just read them into SpatialPolygonsDataFrames and do s12 = rbind(s1,s2), and you end up with a SPDF which has all the features from s1 and s2.

Or do you want to do some geometrical merge operation?
