HI,
Not sure why df2 didn't include Cat3, Debut3, Fin3, instead included columns
with all missing values (Cat5, Debut5, Fin5).
library(plyr)
library(reshape2)
df1New<-ddply(df1,.(Mat),transform,castCat=paste0("Cat",Cat),castDébut=paste0("Début",Cat),castFin=paste0("Fin",Cat))
res<-
join_all(list
Hello,
The following does what you want but the order of columns is different.
reshape(df1, v.names = c("Cat", "Début", "Fin"),
idvar = "Mat", timevar = "Cat", direction = "wide")
Hope this helps,
Rui Barradas
