select.range
accepts two vectors of paired observations and
returns a vector of observations from data
. The observations
returned are those for which the paired values in groupvec
are
within the range specified by min
and max
.
NOTE: The in-range condition is greater than or equal to min
and less than max
. This allows contiguous ranges to be
specified without returning the same value in two sets.
