tibble could lead to an error.decay_logistic().detailed_results to spatial_availability(), used to specify whether results should be aggregated by origin-destination pair or by origin. When aggregation by origin-destination pair, the output also includes the demand, impedance and combined balancing factors used to calculate spatial availability.concentration_index() and theil_t().palma_ratio() and gini_index()) and poverty (fgt_poverty()).spatial_availability() and balancing_cost().cost_to_closest() parameter n now accepts a numeric vector, instead of being restricted to a single number.cumulative_cutoff() parameters cutoff and travel_cost now accepts a numeric and a character vector, respectively, instead of being restricted to a single number/string.cumulative_interval() parameter interval now accepts a list of numeric vectors, instead of being restricted to a single vector.decay_stepped(), both steps and weights can take a list of numeric vectors as input, instead of being restricted to a single numeric vector each).cost_to_closest() would return NA values when filling missing ids (which should be filled with Inf, since they cannot reach any opportunities). This was also responsible for the warning reported in #27, which was also fixed.The package has been to tremendous changes. Basically, there’s not a single part of it that remained untouched: documentation, vignettes, function names, parameter names, extra functionality, performance improvements, etc. While it is impossible to highlight everything that has been done, we’ll try to summary some of the key points in the following topics.

They may not be fully stable and should be used with caution. We make no claims about them.
