Unfortunately, the structure you're asking for doesn't immediately
lend it self to one of R's main data-structures. Where I'd think of
wedging this in would be in a print method, but I'm not sure if that
fits your particular use case.

Something like this [un-tested]:

print.sentiment <- function(x, ...){
   for(i in NROW(x)){
      cat(paste(x[i,]), "\n")
      print(x[i,])
   }
}

with appropriate constructor.

Hopefully this will get you started,
Michael
