[R] looping through 3D array

[arun]

Hi,
Try:
library(emdist)

set.seed(435)
results<- array(sample(1:400,120,replace=TRUE),dim=c(10,3,4)) 
res <- sapply(seq(dim(results)[1]),function(i) {x1 <- results[i,,]; x2 <- results; sapply(seq(dim(x2)[1]),function(i) emd2d(x1,x2[i,,]))})
dim(res)
#[1] 10 10
A.K.

I'll try to be clearer. in your example we have: results<- array(1:120,dim=c(10,3,4)) 

I want to do the following: compare results[1,,] with every matrix inside results. I then want to jump to results[2,,] and compare it to all of the other 10 matrices inside results and so on. so emd2d from the emdist package outputs a single value when comparing matrices and since your example has 10 matrices who are all being compared, the output should be 100 values. 

Does that make sense?
