Unstacks fatalities data by 1) assigning the coordinates of the base case to all cases in a stack and 2) setting the base case as an "address" and making the number of fatalities an attribute.
unstackFatalities(multi.core = FALSE, compute = FALSE,
fatalities = cholera::fixFatalities())
Logical or Numeric. TRUE uses parallel::detectCores(). FALSE uses one, single core. With Numeric, you specify the number logical cores (rounds with as.integer()). On Windows, only "multi.core = FALSE" is available.
Logical. TRUE computes data. FALSE uses pre-computed data.
Corrected fatalities data from cholera::fixFatalities(). For original data, use HistData::Snow.deaths.
An R list that includes anchor.case, fatalities.address, fatalities.unstacked and ortho.proj.
This function is computationally intensive. On a 2.3 GHz Intel Core i7, it takes approximately 5 minutes to run on one core and approximately 70 seconds to run on eight logical (four physical) cores. This function documents the code that generates anchor.case
, fatalities.address
, fatalities.unstacked
and ortho.proj
.
