Analyse species-habitat associations in R. Therefore, information about the
location of the species is needed and about the environmental conditions. To test
for significance habitat associations, one of the two components is randomized.
Methods are mainly based on Plotkin et al. (2000)
plot_randomized_pattern()
now uses envelopes to plot randomized summary functionsplot_randomized_pattern()
includes a quantum barplot_randomized_pattern()
now can return plots after each other (Press )calculate_engery()
can also calculate the energy for marked reconstructionsplot_randomized_pattern()
to plot randomized rastersreconstruct_pattern()
, reconstruct_marks()
and calculate_energy()
rcpp_sample()
as a faster Rcpp implementation of sample()
cat()
with message()
for all printing to consolen_random = 1
comp_fast
argument equals TRUE if number of points exceed thresholdreconstruct_pattern()
stops if energy did not decrease for n iterationsreconstruct_marks()

can also plot point patternsfit_point_process()
