Generate count data for RSTr object — long_to_list

long_to_list_matrix() converts a long table featuring event counts across regions and other optional margins into a list that is readable by *car().

Usage

long_to_list_matrix(
  table,
  event,
  population,
  region,
  group = NULL,
  time = NULL
)

Arguments

table: A table containing event and mortality counts stratified by group/region/time.
event: The column containing event counts.
population: The column containing population counts.
region: The column containing region names.
group: An optional column containing sociodemographic group names.
time: An optional column containing time period names.

Value

A list of mortality and population counts organized into multi-dimensional arrays.

Details

long_to_list_matrix() will sum along any group/time stratifications that aren't specified; for example, if your dataset contains time periods and time is not specified in long_to_list_matrix(), the output will be a sum of all time periods. Filter data by desired groups and time periods before running long_to_list_matrix().

Examples

ma_data <- maexample[!is.na(maexample$Year), ]
# Generates data from 1979-1981 stratified by sex
ma_data_mst <- long_to_list_matrix(ma_data, Deaths, Population, County.Code, Sex.Code, Year.Code)
ma_data_79 <- ma_data[ma_data$Year == 1979, ]
# Generates 1979 data stratified by sex
ma_data_m <- long_to_list_matrix(ma_data_79, Deaths, Population, County.Code, Sex.Code)
# Generates 1979 data summarized for all sexes
ma_data_u <- long_to_list_matrix(ma_data_79, Deaths, Population, County.Code)
