Facilitates the calculation of 40 different insulin sensitivity
    indices based on fasting, oral glucose tolerance test (OGTT), lipid
    (adipose), tracer (palmitate and glycerol rate), and DXA (fat mass)
    measurement values. Enables easy and accurate assessment of insulin
    sensitivity, critical for understanding and managing metabolic disorders
    like diabetes and obesity. Indices calculated are described in
    Gastaldelli (2022) <doi:10.1002/oby.23503>,
    Suleman (2024) <doi:10.1210/clinem/dgae275>, and
    Lorenzo (2010) <doi:10.1210/jc.2010-1144>.

Provides two- and three-way Johnson-Neyman-(Krause) plots for easier interpretation of interactions. It extends the classic framework of Johnson and Neyman (1936) and Johnson and Fay (1950) <doi:10.1007/BF02288864> to Bayesian models and three-way interactions. The functions have dedicated routines for classic lm()/glm() models, as well as 'lme4' models and 'RSiena' results. However, the package can also be used model agnostic and thus extends the availability of JN(K)-plots beyond what is currently available. A detailed introduction can be found in Krause (2026) <doi:10.48550/arXiv.2604.22051>.

Geostatistical interpolation has traditionally been done by manually fitting a variogram and then interpolating. Here, we introduce classes and methods that can do this interpolation automatically. Pebesma et al (2010) gives an overview of the methods behind and possible usage <doi:10.1016/j.cageo.2010.03.019>.

The methods in this package adds to the functionality of  the 'intamap' package, such as bias correction and network optimization. Pebesma et al (2010) gives an overview of the methods behind and possible usage <doi:10.1016/j.cageo.2010.03.019>.

The IntCal20 radiocarbon calibration curves (Reimer et al. 2020 <doi:10.1017/RDC.2020.68>) are provided here in a single data package, together with previous IntCal curves (IntCal13, IntCal09, IntCal04, IntCal98) and postbomb curves. Also provided are functions to copy the curves into memory, and to plot the curves and their underlying data, as well as functions to calibrate radiocarbon dates.
