Map FCDS Incidence Data — fcds_map_add

Two interfaces are provided to mapping funcitonality in R. fcds_map() uses ggplot2::geom_sf() and fcds_map_leaflet() uses leaflet::leaflet() to create static and interactive plots of the input data. The defaults of both functions are designed to work with fcds data, in particular after an age-adjusted rate has been calculated.

fcds_map_add_label(data, ...)

fcds_map(data, ..., fill = rate, geom_sf.color = "grey20",
  geom_sf.size = 0.25, coord_sf_hide = TRUE,
  theme = ggplot2::theme_minimal(),
  scale_fill = ggplot2::scale_fill_viridis_c())

fcds_map_leaflet(data, ..., palette = "Blues", palette_bins = if
  (length(palette == 1)) 5L else length(palette),
  group_name = "year_group",
  group_labels = rev(fcds_const(group_name)), proxy_id = NULL)

Arguments

data	A data frame containing FCDS data. At a minimum either `county_name` or `county_fips` are required to be included in the data. If the input data is not an `sf` data frame, an attempt will be made to join the data with the Florida county boundaries via `join_boundaries_fl()`.
...	Ignored in `fcds_map()`. Additional arguments passed to `leaflet::leaflet()` in `fcds_map_leaflet()`. Additional arguments passed to `glue::glue_data()` in `fcds_map_add_label()`.
fill	The unquoted column name to be used for the fill aesthetic. Defaults to `rate`.
geom_sf.color	The color of the `ggplot2::geom_sf()` shape, typically the color of the county outline.
geom_sf.size	The size of the `ggplot2::geom_sf()` shape, typically the size of the county outline.
coord_sf_hide	If `TRUE` (the default), removes lat/long guides.
theme	The theme to be applied to the plot, by default `ggplot2::theme_minimal()`. Set to `NULL` to use the global ggplot2 default theme.
scale_fill	The fill scale to be applied to the `ggplot2::geom_sf()` shape. By default `ggplot2::scale_fill_viridis_c()`. Set equal to `NULL` to skip the addition of this scale.
palette	Set the color palette of the shape fill. You may provide a vector of colors that will be used for the palette. The number of colors provided determines the number of bins for the values mapped to the fill, unless specified by `palette_bins`.
palette_bins	The number of bins in the color `palette`.
group_name	Character name of the column in `data` containing group layers.
group_labels	Labels for the group levels in the column referenced by `group_name`. These labels should match the values in `data[[group_name]]`.
proxy_id	If provided, a `leaflet::leafletProxy()` map is created instead. For use in Shiny apps.

Value

A ggplot2 plot object

Functions

fcds_map_add_label: Add a column with the name "label" to the input data. The ... are passed to glue::glue_data(), so you can construct labels row-wise with references to the column in data.
fcds_map_leaflet: Creates an interactive map using leaflet::leaflet().

Examples

fcds_example_rates <-
  fcds::fcds_example %>%
  count_fcds(moffitt_catchment = TRUE) %>%
  complete_age_groups(county_name, tidyr::nesting(year_group, year)) %>%
  age_adjust() %>%
  dplyr::ungroup() %>%
  dplyr::mutate(rate = rate / 5) %>%
  dplyr::mutate(year_group = factor(year_group, unique(year_group)))
#> Warning: The moffitt_catchment argument is deprecated, please use county_name = "moffitt"

if (all(fcds:::suggests_package(c("sf", "ggplot2")))) {
  fcds_map(fcds_example_rates) +
    ggplot2::facet_wrap(~year_group, ncol = 4) +
    ggplot2::theme(legend.position = c(0.93, 0.25))
}

if (FALSE) {
fcds_map_leaflet(fcds_example_rates)
