inAccessMod: An R package to automate data downloading and processing for AccessMod

inAccessMod is an R package that allows the user to easily download and prepare all the required layers for the World Health Organization-recognized AccessMod software used to model physical accessibility to health care. The layer downloading, cropping, masking, projecting, resampling processes are automated to a large degree, making the preparation of the inputs quick and straightforward. The package includes additional functions to modify inputs and facilitate complex analyses (e.g. sub-national travel scenarios), to handle health facility data from The Health Resources and Services Availability Monitoring System (HeRAMS), and to perform specific result assessments (e.g. ranking of health facilities based on their coverage).
