get.symbol returns the chemical symbol for an atom.get.point3d returns the 3D coordinates of the atom
get.point2d returns the 2D coordinates of the atom
get.atomic.number returns the atomic number of the atom
get.hydrogen.count returns the number of implicit H's on the atom.
Depending on where the molecule was read from this may be NULL or an integer
greater than or equal to 0
is.aromatic returns TRUE if the atom is aromatic, FALSE
otherwise
is.aliphatic returns TRUE if the atom is part of an aliphatic chain,
FALSE otherwise
is.in.ring returns TRUE if the atom is in a ring, FALSE
otherwise

is.in.ring(atom)jObjRef representing an IAtom objectget.point3d the return value is a
3-element vector containing the X, Y and Z coordinates of the
atom. If the atom does not have 3D coordinates, it returns a
vector of the form c(NA,NA,NA). Similarly for
get.point2d, in which case the return vector is of
length 2.get.atoms
