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). 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)]
Matricule Nom Debut Fin
1 1 VERON 24/01/1995 31/12/1997

10 934 FORNI 05/09/2012 31/12/4712
df2[,c(1,2,7:8)]
Mat Nom Debut Fin
1 1 VERON 24/01/1995 31/12/1997
2 6 BENARD 02/02/1995 12/03/1995
3 6 BENARD 13/03/1995 30/06/1995
4 6 BENARD 01/01/1996 31/01/1996 #missing this row
5 8 DALNIC 24/01/1995 31/08/1995
6 8 DALNIC 01/09/1995 29/02/2000
7 934 FORNI 26/01/1995 31/08/2001

9 934 FORNI 01/09/2004 31/08/2007
10 934 FORNI 01/09/2007 04/09/2012
11 934 FORNI 05/09/2012 31/12/4712
Here, the dates look similar to the ones on df2 except for one row in df2.

Subject: [R] simplify a dataframe
Hello
I have the following problem : group the lines of a dataframe when no
information change (Matricule, Nom, Sexe, DateNaissance, Contrat, Pays)
and when the value of Debut of lines i = value Fin of lines i-1
I can obtain it with a do loop. Is it possible to avoid the loop ?
The dataframe initial is df1
dput(df1)
