mapDetections: Create a Map Showing Numbers of Detections

In EricArcher/PAMsbuoy: Manipulation and filtering for PAM (Passive Acoustic Monitoring) data collected from sonobuoys

Description

Return a ggmap object showing the number of detections at each sonobuoy station. Can show maps for all detections, or broken up by species.

Usage

mapDetections(
  detectionData,
  species = "all",
  combine = TRUE,
  value = "NumDetections",
  map = NULL,
  size = 3,
  ncol = 3,
  palette = "Reds",
  nGroups = 6,
  grouping = "station"
)

Arguments

detectionData	a dataframe with data on detections. Must have columns Latitude, Longitude, Station, and Count. Must also have column Species unless bySpecies is 'none'
species	The species to look at. Either a vector of specific species, or 'all' to use all species.
combine	Should the counts for the selected species be combined. If FALSE, graph will be faceted for each species.
value	column name of values to plot
map	Optional, a ggmap object to plot on. If left as NULL, will be created by the getMap function. Can be included to reduce calls to getMap.
size	Size of points to be plotted
ncol	number of columns when plotting multiple species
palette	color palette to be used, see brewer.pal for more info
nGroups	the number of different groups to use for coloring. Groups will be evenly spaced between 0 and max number of detections.
grouping	The level to group count data by. Default is Station, can be set to c('Station', 'Buoy') to group at buoy level.
