spTransform function in rgdal will do this, but UTM is a family of projections so you need at least to know which zone is appropriate and whether it is even any kind of sensible choice for projecting your coordinates to. What is the range of the data and for what purpose do you need them projected?
It really matters since every projection is a compromise with pretty restrictive limitations.
