Examples

## 2x2 array
x <- parray(c("a","b"), levels=c(2,2), values=1:4)

## Simulate from entire array
s <-simulateArray(x,1000)
xtabs(~., as.data.frame(s))

## Simulate from slice defined by that dimension 1 is fixed at level 2
s <-simulateArray(x,6000,1,2)
xtabs(~., as.data.frame(s))

## 2x2x2 array
x <- parray(c("a","b","c"), levels=c(2,2,2), values=1:8)

## Simulate from entire array
s <-simulateArray(x,36000)
xtabs(~., as.data.frame(s))

## Simulate from slice defined by that dimension 3 is fixed at level 1
s <-simulateArray(x,10000,3,1)
xtabs(~., as.data.frame(s))
