so want extract slot "coords" [[1]] in dataframe ,slot "coords" from[[2]] in dataframe on...

can help me please?

edit :

for example, extracting coordinates???

[1,] 5.6828 20.7764 [2,] 5.7828 20.7764 [3,] 5.8828 20.7764 [4,] 5.9828 20.7764 [5,] 5.9828 20.3764 [6,] 5.8828 20.3764 [7,] 5.7828 20.3764 [8,] 5.6828 20.3764 [9,] 5.5828 20.3764 [10,] 5.5828 20.7764 [11,] 5.6828 20.7764

wouldn't be?

name_of_list_of_objects[[1]]@coords

usually there extraction function s4 object considered safer , more correct, might work:

coordinates( name_of_list_object[[1]] )

so multiple items, just:

lapply(name_of_list_of_objects, coordinates)

r polygons slot
