You sent this to the R-help list, not just to Arun, so I'm assuming
this is an R question. The best way to get help is to provide a sample
of your data using dput() and to clearly specify what you would like
as the result - "unify" is a bit vague. paste(x,
collapse="") could be
considered unification, after all.
