Replicate values in one vector based on consecutive entries in a second
vector. Useful for adding per-residue data to all-atom PDB files.
Usage
vec2resno(vec, resno)
Value
Returns a vector of replicated values.
Arguments
vec
a vector of values to be replicated.
resno
a reference vector or a PDB structure object, obtained
from read.pdb, upon which replication is based.

Details
This function can aid in mapping data to PDB structure files. For
example, residue conservation per position (or any other one value per
residue data) can be replicated to fit the B-factor field of an all
atom PDB file which can then be rendered according to this field in a
molecular viewer.
A basic check is made to ensure that the number of consecutively
unique entries in the reference vector equals the length of the vector
to be replicated.
