How to export a dataset with "SpatialPolygonsDataFrame" as a shapefile

[المشرف العام]

How to export spatial datasets in R, such as "tornados" dataset in "GISTools" package, as a shapefile with the exact same spatial reference and the exact values?

Library(GISTools)

data(tornados)

"SpatialPolygonsDataFrame" to "shapefile"---"SpatialPointsDataFrame" to "shapefile"---"(Forced) SpatialPointsDataFrame" to "shapefile"---"(Non-Forced) SpatialPointsDataFrame" to "shapefile"---"SpatialLinesDataFrame" to "shapefile".

Thanks.
