"0" is counted as 1 object.
Of course! It is a number like any other.
Does "object length" mean the total number of objects/entries?
Yes.
Please help me to understand follow;
"For example if the dimension vector for an array, say a, is c(3,4,2) then there
are 3 * 4 * 2 = 24 entries in a and the data vector holds them in the order
a[1,1,1], a[2,1,1], ..., a[2,4,2], a[3,4,2]."
I don't understand;
a[1,1,1], a[2,1,1], ..., a[2,4,2]
[snip]
A[i, j, k] is the value of the element in position (i,j,k) of array A. In
other words, it is the entry in row i, column j, and "layer" k (if one
wants to think of A as a cuboidal grid).
