In afrimapr/afrihealthsites: Geographic locations of African health facilities from different sources

Description

main aim to plot map comparing different sources

Usage

compare_hs_sources(
  country,
  datasources = c("healthsites", "who"),
  plot = "mapview",
  plotshow = TRUE,
  plotcex = c(6, 4),
  col.regions = list(RColorBrewer::brewer.pal(9, "YlGn"), RColorBrewer::brewer.pal(9,
    "BuPu")),
  alpha = c(0.1, 0.1),
  alpha.regions = c(0.7, 0.7),
  layer.names = NULL,
  plotlegend = TRUE,
  hs_amenity = "all",
  who_type = "all",
  canvas = FALSE,
  plotlabels1 = FALSE,
  plotlabels2 = FALSE,
  map.types = c("CartoDB.Positron", "OpenStreetMap.HOT"),
  type_column = "Facility Type",
  label_column = "Facility Name",
  lonlat_columns = c("Longitude", "Latitude"),
  admin_level = NULL,
  admin_names = NULL
)

Arguments

country	a character vector of country names or iso3c character codes.
datasources	vector of 2 datasources from 'healthsites' predownloaded, 'who', 'healthsites_live' needs API, 'hdx' not working yet
plot	option to display map 'mapview' for interactive, 'sf' for static
plotshow	whether to show the plot, otherwiser just return plot object
plotcex	sizes of symbols for each source default=c(6,3), helps view symbol overlap
col.regions	list of two colour palettes to pass to mapview
alpha	list of two alphas to pass to mapview - low keeps borders light
alpha.regions	list of two alpha.regions to pass to mapview
layer.names	allow mapview layer.names to be set c('a','b')
plotlegend	whether to add legend to mapview plot
hs_amenity	filter healthsites data by amenity. 'all', 'clinic', 'dentist', 'doctors', 'pharmacy', 'hospital'
who_type	filter by Facility type
canvas	mapview plotting option, TRUE by default for better performance with larger data
plotlabels1	whether to add static labels for source1
plotlabels2	whether to add static labels for source2
map.types	optional specification of background map tiles for mapview, default c('CartoDB.Positron','OpenStreetMap.HOT')
type_column	just for user provided files which column has information on type of site, default : 'Facility Type'
label_column	just for user provided files which column has information on name of site, default : 'Facility Name'
lonlat_columns	for user provided files which columns contain longitude, latitude. option of NULL if no coords
admin_level	what admin level to filter regions from FALSE or NULL if no filtering
admin_names	names of admin regions to filter NULL if no filter

Value

sf

Examples

#compare_hs_sources("nigeria", datasources=c('who', 'healthsites'), plot='mapview')
#compare_hs_sources(c('malawi','zambia'))

#filter by admin regions
compare_hs_sources('togo', admin_level=1, admin_names=c('Maritime Region', 'Centrale Region'))
