Sincerely,

See functions ?project and ?spTransform in the rgdal package. The
former is simpler but is only for transforming  a matrix of
coordinates from or to longitude / latitude, and no datum
transformation is possible. The latter can transform Spatial* objects
arbitrarily from or or to any PROJ.4 coordinate system and includes
datum transformations.
