myNorm: myNorm

In majpark21/TSexploreR: Explorative Tools for Time Series

Description

Returns original dt with an additional column with normalized quantity. Normalisation is based on part of the trajectory.

Usage

myNorm(in.dt, in.meas.col, in.rt.col = "RealTime", in.rt.min = 10,
  in.rt.max = 20, in.by.cols = NULL, in.robust = TRUE,
  in.type = "z.score")

Arguments

in.dt	data.table, contain a column for: time, measurement(, grouping columns like object label)
in.meas.col	character, name of column to be normalised.
in.rt.col	character, name of the column with time (or index)
in.rt.min	numeric, start time of normalization period.
in.rt.max	numeric, end time of normalization period.
in.by.cols	character vector with 'by' columns to calculate normalisation per group if NULL, no grouping is done
in.robust	logical, whether robust measures should be used (median instead of mean, mad instead of sd).
in.type	type of normalization: 'z.score' or 'mean' (fi.e. old change w.r.t. mean)

Value

A data.table with an additional column with normalized quantity. The name of additional column is the same as in.meas.col but with ".norm" suffix added.
