cluster1d: Group one-dimensional data into clusters of contiguous points

In cbaumbach/miscFun: Miscellaneous functions

Description

Group one-dimensional data into clusters of contiguous points

Usage

cluster1d(x, gap, frac = NULL)

Arguments

x	Numeric vector of points to be grouped into clusters
gap	Size of gap that separates two neighboring clusters
frac	Size of gap that separates two neighboring clusters expressed as a fraction of the range of ‘x’

Value

Returns an integer vector that is aligned with ‘x’ and contains the cluster for the associated element in ‘x’. NA values in ‘x’ will have NA values in the resulting vector.

Examples

x <- c(9, 12, 3, 4, 17, 10, 12, NA, 6, 1)
cluster1d(x, gap = 3)
cluster1d(x, frac = .15)
