Hi
For a dataframe with name PaysContrat1 and with
nrow(PaysContrat1)
[1] 52366
the test of system.time is :
system.time(droplevels(do.call(rbind,lapply(split(PaysContrat1,PaysContrat1$Matricule),
FUN=function(x) {x[,c(Nom,Prénom)] -
x[nrow(x),c(Nom,Prénom),drop=TRUE];x}

But I just noticed that the two solutions are not comparable :
the change concern only Nom and Prenom (solution Berend) and not also
Sexe or Date.de.naissance orother variables (solution Arun) that can

Based upon the subsequent exchange with Rich late yesterday, I could not

not automatically remove empty levels but you can do it:

Here's an approach that seems to work. I added an 11th case to
your data since you did not have a case where both Left and
Right had multiple values in the lookup table. This creates an
id value so that we can merge left and right separately and
then merge them back together:
