If you mean profiles as in correspondence analysis, just do:

( assuming your table is mytab)
N <- sum(mytab)
Nr <- rowSums(mytab)
Nc <- colSums(mytab)
perfRow <- mytab
for (i in 1:NROW(mytab)) }{
     perfRow[i,] <- perfRow[i,]/Nr[i] }

perfRow

and then you can just plot them, maybe using lines().

But have a look into ?mosaicplot
