Group values with a difference between them being smaller than a user
defined threshold. This function uses the groupSimilarityMatrix()
function
to create groups with smallest differences between its members. Differences
between all members of one group are below the user defined threshold
maxDiff
. This is a more stringent grouping than what groupConsecutive()
performs leading thus to smaller groups (with smaller differences between
its members).
Arguments
- x
numeric
of values that should be grouped.- maxDiff
numeric(1)
defining the threshold for difference between values inx
to be grouped into the same group.

Examples
x <- c(1.1, 1.9, 2.2)
groupClosest(x)
#> [1] 2 1 1
## Although the difference between the 1st and 2nd element would be smaller
## than the threshold, they are not grouped because the difference between
## the 2nd and 3rd element is even smaller. The first element is also not
## put into the same group, because it has a difference > diffRt to the 3rd
## element.
x <- c(1.1, 1.5, 1.7, 2.3, 2.7, 4.3, 4.4, 4.9, 5.2, 5.4, 5.8, 6, 7,
9, 9.5, 15)
groupClosest(x)
#> [1] 2 2 2 5 5 1 1 3 3 3 4 4 7 6 6 8
