Hi listers,
I have the following code...
data<-as.matrix(c(1,2,3,4,5,6,7,8,9,10),nrow=10,ncol=1,byrow=TRUE)
n<-nrow(data)
m<-n-1
boot<-data[sample(m,replace=T),]
So, I need to count the number of times each observation was selected at the
sample with replacement...
Suppose I sampled...
4 5 1 3 7 5 1 4 7
So, I would count...
x count
1 2
2 0
3 1
4 2
5 2
6 0
7 2
8 0
9 0
10 0
Thanks in advance,
Marcio
