check_repetition: Check for repetition in the series

In rpatin/segtools: Bivariate Segmentation/Clustering Methods and Tools

Check for repetition in the series

Description

check_repetition checks whether the series have identical or near-identical repetition larger than lmin. if that is the case, throw an error, the algorithm cannot yet handle these repetition, because variance on the segment would be null.

Usage

check_repetition(x, lmin, rounding = FALSE, magnitude = 3)

Arguments

x	the bivariate series to be tested
lmin	minimum length of segment
rounding	whether or not series are rounded
magnitude	number of magnitude of standard deviation below which values are rounded. i.e if magnitude = 3, difference smaller than one thousandth of the standard deviation are rounded to the same value.

Value

a boolean, TRUE if there is any repetition larger or equal to lmin.

Examples

set.seed(42) 
dat <- rbind(base::sample(seq(1,10),  size= 100, replace = TRUE),
             base::sample(seq(1,10),  size= 100, replace = TRUE))
check_repetition(dat, lmin = 3)
check_repetition(dat, lmin = 5)
