In YuriNiella/RSP: Refined Shortest Paths

Add group centroid location to an existing plot

Description

Add group centroid location to an existing plot

Usage

addCentroids(
  input,
  type,
  tag = NULL,
  track = NULL,
  timeslot = NULL,
  shape = 21,
  size = 1.5,
  colour = "white",
  fill = "cyan"
)

Arguments

input	The output of getCentroids
type	One of "group" or "track".
tag	Animal of interest, when type = "track".
track	Track of interest, when type = "track".
timeslot	The timeslot of interest to plot the centroid location
shape	The shape of the points
size	The size of the points
colour	The colour of the points
fill	The fill of the points

Value

A ggplot with centroid locations

Examples

# Import river shapefile
water <- actel::shapeToRaster(shape = paste0(system.file(package = "RSP"), "/River_latlon.shp"), 
size = 0.0001, buffer = 0.05) 

# Create a transition layer with 8 directions
tl <- actel::transitionLayer(x = water, directions = 8)

# Import example output from actel::explore() 
data(input.example) 

# Run RSP analysis
rsp.data <- runRSP(input = input.example, t.layer = tl, coord.x = "Longitude", coord.y = "Latitude")

# Run dynamic Brownian Bridge Movement Model (dBBMM) with timeslots:
dbbmm.data <- dynBBMM(input = rsp.data, base.raster = water, UTM = 56, timeframe = 2)

# Get dBBMM areas at group level
areas.group <- getAreas(dbbmm.data, type = "group", breaks = c(0.5, 0.95))

# Obtaing centroid coordinate locations of dBBMM:
df.centroid <- getCentroids(input = dbbmm.data, type = "group", areas = areas.group, 
   level = 0.95, group = "G1", UTM = 56)

# Plot group centroid location:
plotAreas(areas.group, base.raster = water, group = "G1", timeslot = 7) +
   addCentroids(input = df.centroid, type = "group", timeslot = 7)
