[R] Finding overlaps in vector

posted mailed Dear all, I'm trying to solve the problem, of how to find clusters of values in a vector that are closer than a given value. Illustrated this might look as follows: vector - c(0,0.45,1,2,3,3.25,3.33,3.75,4.1,5,6,6.45,7,7.1,8) When using '0.5' as the proximity requirement, the

Re: [R] Sorting factors

By default, factors are characters and sorted in alphabetical order. It looks like somehow you numeric data was converted to factors. Therefore '10' comes before '2'. If you want the factors in numeric order you have to convert them back. Look in the FAQs. x - c(1,2,3,4,5,10,11,20,21,22,30)

Thank you very much for this elegant solution to the problem. The reason I still hope for an extension of Jim's code (not the one re responded with in this thread, but the one I actually reference) is that windows of overlap can be asymetric with that: one can check e.g. whether values overlap
