It seems that Xi is a matrix; so it can't be included in a vector.

You need to create a list for the result of your "for" loop.

res <- list()

for ( i in ...) {

res[[i]] <-  Xi }

Dear statisticians,

I would like to save results for a "for loop" in a vector previously created.
My result would be of class "matrix".

I tried the following script:

Script:
#Creation of a previous vector
n.Tree<-2
VectorX<-rep(1,n.Tree)

#loop
for (i in 1:2) {
Ti<-MatOccurTree[Tree[i],1] #number of observation for Tree i
Xi<-matrix(data=1,nrow=Ti,ncol=2)
Xi[,2]<-treedata2$lnE[IdentTree==Tree[i]]
VectorX[i]<-Xi
}

Console:

VectorX[i]<-Xi

Warning message:
le nombre d'objets ?? remplacer n'est pas multiple de la taille du remplacement 
"number of object to replace isn't a multiple of the length of the replacement"

Would you have any solution to create a vector of matrix "VectorX" ?

Thanks for your help.

Ghislain Vieilledent.
