Dear all,
I would like to select from a vector of 10 elements, 5 of those that are
identical.
How can I do that in R? I guess one way would be to taking random numbers and
see if that appeared again. Is though there a more straightforward approach?
Regards
Alex

Use 'table' to count the occurances and then select the one that has a
count of 5.

What is the problem that you are trying to solve?
Tell me what you want to do, not how you want to do it.

But just noting the usual floating point stuff, Jim's approach might
run into problems depending on what you have as numbers and what is
meant by identical.

Hi,
I want from a vector containing has like 1000 elements to select X of it
randomly but with never selecting the same element again. Each one should be
unique element of the vector.
Is this more precise now?
Regards
Alex
