[R] Creating a ragged array

[Barth B. Riley]

Dear list

I am trying to figure out how to create a ragged array that consists of groups of array elements (indices from the original array) of similar values. I would like to create a ragged array that might look something like this:

S[1]
11, 19, 14,7

S[2]
29,4,1,13,44

S[3]
56,9,2,35

S[4]
3,5

...

Thanks in advance

Barth
