Create a global map of dataset geographic distribution

Source: R/map_utils.R
create_data_map.Rd

Plots each dataset entry as a dot on a world map. Dot size is proportional to log(n+1) and dot colour indicates pathogen. Datasets with country = "Mixed" are excluded from the map and listed in an inset box.

Usage

create_data_map(
  data = NULL,
  exclude_no_n = FALSE,
  default_n_log = 1.5,
  alpha = 0.6,
  jitter_amount = 3,
  title = "Geographic distribution of delay distribution datasets"
)

Arguments

data

A data frame from extract_dataset_summary(). If NULL, extract_dataset_summary() is called internally.

exclude_no_n

Logical. If TRUE, entries with missing sample size are dropped. If FALSE (default), they appear at size default_n_log.

default_n_log

Numeric. Log-scale dot size used when n is missing.

alpha

Numeric (0–1). Point transparency.

jitter_amount

Numeric. Maximum spatial jitter in degrees lat/lon, applied to separate overlapping points from the same country.

title

Character. Plot title.

Value

A ggplot2::ggplot() object.

Details

For reproducible jitter, call set.seed() before this function.
