Hello,
If you just want the dimensions of the array, and assuming the input list
will give
a rectangular array with no need to use NA's, the function below works.
(It doesn't construct the array)
aa <- list(list(list(1:4),
list(5:8),
list(9:12)),
list(list(13:16),
list(17:20),
list(21:24)))
bb <- list(aa, aa, aa, aa, aa)
fun <- function(lst){
d <- ix <- 0
while(length(lst) > 1){
d[ix <- ix+1] <- length(lst)
lst <- lst[[1]]
}
d[ix+1] <- length(lst[[1]])
d
}
fun(aa)
fun(bb)
fun(list(aa, bb)) # not rectangular, therefore
fun(list(bb, aa)) # different results
