you are right.by labels I mean the "categories", "breaks"
that my data fall in.To be part of group 2 for example you have to be in the
range of [110,223) I need to keep those for my plots.
Did I describe it more precisely now?Alex

These are simple operations that should not add perceptibly to execution time.

The breaks are just the min() and max() in your groups. Something like
sprintf("[%5.2f,%5.2f]", min(dBin[groups==2]), max(dBin[groups==2]))
... should achieve what you need.

Whatever approach is "best" to define subsets depends completely on the semantics of the data. Your approach (a fixed number of equally spaced breaks) is the right one if the absolute ranges of the data is important. It should be obvious that either the top or the bottom group could contain only a single element, and also that any or all of the intermediate groups could be empty. If you want to control the number of elements in your groups, use quantiles instead. Your application may require to define the breaks in other ways. The code I have given you doesn't generalize well, as it depends on the equal spacing of breaks. As I mentioned earlier, I would not store the groups at all - but would define a function that returns a vector of elements in the group, and in the function body I would clearly and explicitly define the conditions for group membership (and comment it). That is how you make code for a task like this explicit and _maintainable_.

Thanks for your comments. Actually only the last group has a single element. The
first group is always "full" of members and as that it works fine.
Some constant spacing between the groups would be good as well and thus I will
check quantiles.
Thanks for the great support and time invested on thisRegardsAlex

define a function that returns a vector of elements in the group, and in the
function body I would clearly and explicitly define the conditions for group
membership (and comment it). That is how you make code for a task like this
explicit and _maintainable_.

keep these groups in a column adjacent to your values, rather than in a separate
vector, or even better to just calculate the groups on the fly in your
downstream analysis with the approach given above in a function, rather than
storing them at all. These are simple operations that should not add perceptibly
to execution time.
