This package brings together HyperTraPS(-CT), HyperHMM, HyperLAU, HyperDAGs and HyperMk, different algorithms for accumulation modelling. All are based around the idea of inferring hypercubic transition graphs that describe the accumulation of binary features.

Wrapper function hyperinf produces fitted hypercubic inference models from data; plot_hyperinf produces summary plots of the inferred transition graph. Arguments to hyperinf specify which fitting approach to use (default is to choose based on data structure). full_to_squared_fit converts a fully-parameterised hypercube (including those output from HyperHMM, HyperMK, HyperLAU) to a best estimate of an L2-parameterised HyperTraPS model (encoding pairwise interactions between features). plot_hyperinf_comparative and plot_hyperinf_bubbles produce comparative plots summarising dynamics across a list of model fits; plot_hyperinf_bootstrap compares bubble plots from two bootstrapped model fits.
This will check and demo some of the functionality, based on HyperHMM. A more illustrative test bed is in inst/test-bed.R.
library(hyperinf)
# construct a simple dataset
data = matrix(rep(c(0,0,1, 0,1,1, 1,1,1), 10), byrow = TRUE, ncol=3, nrow=30)
# do model fits with bootstrapping to this dataset and its "inverse"
fit.1 = hyperinf(data, boot.parallel = 50)
fit.2 = hyperinf(1-data, boot.parallel = 50)
# plot the data
plot_hyperinf_data(data)
# plot a single model fit
plot_hyperinf(fit.1)
# compare transition networks
plot_hyperinf_comparative(list(fit.1, fit.2))
# compare summary "bubble" plots
plot_hyperinf_bubbles(list(fit.1, fit.2), p.scale = 0.2)
# compare bootstrapped bubble plots
plot_hyperinf_bootstrap(fit.1, fit.2)
