Dear all,
to make our life easier, I give you the following dataset (just this
vector) and code! It gives me two arrays of different dimensions: the first
is a 2x2x1 array and the second is a 2x2x2 array (please, feel free to
correct me on the way I define the arrays. This is the first time I am
working on them).
What I want to achieve is to create 10 2x2 matrices in the first array, 5
2x2 matrices and 3 2x2 matrices in the first and second row, respectively,
of the second array. Feel free to give any data in the matrices!
All I need is to understand where exactly I have stuck in my code! This is
a part of my (horribly large) code. Once I realise where my problem is,
then I would be able to have results! All I need is a small "push" from the
team!:)
Again thank you very much for your patience!!!
All the best,
Loukia
t = c( 1 , 2, 2 ) # Interventions
tn<-as.vector(table(t))
results<-vector("list",length(unique(t)))
for(i in 1:length(unique(t))){
results[[i]]<-array(dim=c(2,2,tn[i]))
k<-1
results[[i]][,,k]
k<-k+1
}
results
