peanutButter: An R package to produce rapid-response gridded population estimates from building footprints, version 0.2.1.

peanutButter is an R package that allows you to produce gridded population estimates from building footprints using the "peanut butter" method of spreading people evenly among buildings based on a set of simple parameters. This package allows you to: 1) produce gridded population estimates using a bottom-up approach that applies your estimates of average people per building for urban and rural areas to each building in the corresponding settlement type, 2) produce gridded population estimates using a top-down approach that dissaggregates your population totals for administrative units evenly among buildings such that the population total per administrative unit matches those defined by the user, 3) produce gridded population estimates for specific demographic groups (i.e. age and sex), and 4) run the peanutButter Shiny application locally from the R console for a graphical user interface.
