Parse, trim, join, visualise and analyse data from Itrax sediment core multi-parameter
scanners manufactured by Cox Analytical Systems, Sweden. Functions are provided for parsing
XRF-peak area files, line-scan optical images, and radiographic images, alongside accompanying metadata.
A variety of data wrangling tasks like trimming, joining and reducing XRF-peak area data are simplified.
Multivariate methods are implemented with appropriate data transformation.

This package is based on the code of the rpart package.
It extends rpart by adding additional splitting methods
emphasizing interpretable/parsimonious trees.  Unless indicated
otherwise, it is safe to assume that all functions herein are
extensions of or copied directly from similar or nearly
identical rpart methods.  As such, the authors of rpart are
authors of this package as well.  However, please direct any
error reports or other questions about itree to the maintainer
of this package; they are welcome and appreciated.

Running Interrupted Time Series Analysis
Two functions for running and then post-estimating an Interrupted Time Series Analysis model. This is a solution for running time series analyses on temporally short data. See English (2019) 'The its.analysis R package - Modelling short time series data' <https://papers.ssrn.com/sol3/papers.cfm?abstract_id=3398189> for an overview of the method.
