Provides data frames that hold certain columns and attributes 
    persistently for data processing in 'dplyr'.

A collection of functions for processing raw data from Stream Temperature, Intermittency, and Conductivity (STIC) loggers. 'STICr' (pronounced "sticker") includes functions for tidying, calibrating, classifying, and doing quality checks on data from STIC sensors. Some package functionality is described in Wheeler/Zipper et al. (2023) <doi:10.31223/X5636K>.

Manipulating input and output files of the 'STICS' crop
    model. Files are either 'JavaSTICS' XML files or text files used by
    the model 'fortran' executable. Most basic functionalities are reading
    or writing parameter names and values in both XML or text input files,
    and getting data from output files.  Advanced functionalities include
    XML files generation from XML templates and/or spreadsheets, or text
    files generation from XML files by using 'xslt' transformation.

Functions for simplified emulation of time series computer model output in model parameter space using Gaussian processes. Stilt can be used more generally for Kriging of spatio-temporal fields. There are functions to predict at new parameter settings, to test the emulator using cross-validation (which includes information on 95% confidence interval empirical coverage), and to produce contour plots over 2D slices in model parameter space.

The goal of 'stim' is to provide a function for estimating the Stability Informed Model. The Stability Informed Model integrates stability information (how much a variable correlates with itself in the future) into cross-sectional estimates.

Regression trunk model estimation proposed by Dusseldorp and Meulman (2004) <doi:10.1007/bf02295641> and Dusseldorp, Conversano, Van Os (2010) <doi:10.1198/jcgs.2010.06089>, integrating a regression tree and a multiple regression model.

A consistently well behaved method of interpolation based on piecewise rational functions using Stineman's algorithm.
