I would like generate a list, or a matrix, containing all the combinations among qualitative data or object (es. words) conteined in a string (es. .csv), without any constraint about position.
In Microsoft Excel I found a function (combine.value) that calcule the number of combination with repetition, with specification of list of value (“numbers”) and “class”, that is the dimension of extracted samples. For example, I have 12 different object (words) and would like generate all the combination among them, with the only constraint that all combination must contain 15 object. Combine.value for 18 objects and 15 class, give 7.726.160 different combination.
My problem now isn’t calculate how many combinations is possible produce, but… produce them!
Thank everybody in advance!
