HI Michel,
This gives the same order as that of df2.
df1$contrat[grep("^CDD",df1$contrat)]<- "CDD détaché ext. Cirad"
df1[48,8]<- "31/12/2013"
indx<-as.numeric(interaction(df1[,1:6],drop=TRUE))
lst1<-split(df1,indx)
lst2<-lst1[match(unique(indx),names(lst1))]
res<-do.call(rbind,lapply(lst2,function(x){x1<- as.Date(x$Debut,format="%d/%m/%Y");x2<-
as.Date(x$Fin,format="%d/%m/%Y");do.call(rbind,lapply(split(x,cumsum(c(FALSE,(x1[-1]-x2[-nrow(x)])!=1))),function(x)
data.frame(x[1,1:6],Debut=head(x$Debut,1),Fin=tail(x$Fin,1),stringsAsFactors=FALSE)))}))
row.names(res)<- 1:nrow(res)
df2[11,8]<- "31/12/2013"
names(res)[1]<- "Mat"
identical(res,df2)
#[1] TRUE

Hi,
Excuse me for the indistinctness
Le 13/07/2013 17:18, arun a écrit :
Hi,
"when the value of Debut of lines i = value Fin of lines i-1"
That part is not clear esp. when it is looked upon with the expected output
(df2).
I want to group the lines which have the same caracteristics (Matricule, Nom,
Sexe, DateNaissance, Contrat, Pays) and with period of time (Debut/start and
Fin/end) without interruption of time.
For exemple :
The following three lines
:
Debut/Start Fin/End
1 VERON Féminin 02/09/1935 CDI commun France 24/01/1995
30/04/1997
1 VERON Féminin 02/09/1935 CDI commun France
01/05/1997 30/12/1997
1 VERON Féminin 02/09/1935 CDI commun France
31/12/1997 31/12/1997
are transformed into 1 line
1 VERON Féminin 02/09/1935 CDI commun France 24/01/1995
31/12/1997
because same caracteristicsand period of time without interruption
of time (from 24/01/1995 to 31/12/1997)
The following six lines :
6 BENARD Masculin 01/04/1935 CDI commun Philippines 02/02/1995
27/02/1995
6 BENARD Masculin 01/04/1935 CDI commun Philippines
28/02/1995 28/02/1995
6 BENARD Masculin 01/04/1935 CDI commun Philippines
01/03/1995 12/03/1995
6 BENARD Masculin 01/04/1935 CDI commun France 13/03/1995
30/06/1995
6 BENARD Masculin 01/04/1935 CDI commun France 01/01/1996
30/01/1996
6 BENARD Masculin 01/04/1935 CDI commun France
31/01/1996 31/01/1996
are transformed into
6 BENARD Masculin 01/04/1935 CDI commun Philippines 02/02/1995
12/03/1995
6 BENARD Masculin 01/04/1935 CDI commun France 13/03/1995
30/06/1995
6 BENARD Masculin 01/04/1935 CDI commun France 01/01/1996
31/01/1996
because
lines 1-3 identical for caracteristics and without interruption in
time
lines 4 and lines 5-6 are not grouped because there is an
interruption in time beetween 30/06/1995 and 01/01/1996
Thank you for your help
Michel
Also, in your example dataset: df1$contrat[grep("^CDD",df1$contrat)]
#[1] "CDD détaché ext. Cirad" "CDD détaché ext. Cirad" "CDD détaché ext. Cirad"
#[4] "CDD détaché ext. Cirad" "CDD détaché ext.Cirad" "CDD détaché ext. Cirad"
#[7] "CDD détaché ext. Cirad" "CDD détaché ext.Cirad" "CDD détaché ext. Cirad"
##Looks like there are extra spaces in some of them. I guess these are the same
df1$contrat[grep("^CDD",df1$contrat)]<- "CDD détaché ext. Cirad" I tried this:
indx<-as.numeric(interaction(df1[,1:6],drop=FALSE)) df1New<- df1
res2<-unique(within(df1New,{Debut<-ave(seq_along(indx),indx,FUN=function(x)
Debut[head(x,1)]);Fin<- ave(seq_along(indx),indx,FUN=function(x) Fin[tail(x,1)])}))
row.names(res2)<- 1:nrow(res2) res2[,c(1,2,7:8)]
