Even if it's not so elegant, I will bind it in a function, so I don't have to
bother with that anymore. I think there should be a simple function in R to
initialize an empty data frame. From what I've read, it is a recurrent
question on that list.
#Create an empty data frame from a header list
empty.df<- function(header){
df<-data.frame(matrix(matrix(rep(1,length(header)),1),1))
colnames(df)<-header
return(df[NULL,])
}
# Usage
new.df <- empty.df(paste("A",1:5,sep=""))
> new.df
[1] A1 A2 A3 A4 A5
<0 rows> (or 0-length row.names)
Thanks again,
Etienne
