Environment-class: Environment Constructor

In aqvining/Foraging-Simulator: Simulating Forager Movement In Environments With Discrete Resource Distributions

Environment Constructor

Description

Constructor Function for objects of Reference Class 'Environment'

Fields

foragers

a list containing Reference Class objects that inherit from 'Forager' class.

patches

a simple feature data frame with geometries representing patches in the geometry column

bounds

a spatial features collection with one or more polygons defining the region in which any foragers can be created and moved to

Methods

initialize( ..., patches = lapply(rep(2, times = 10), function(x) st_point(runif(x, min = -15, max = 15))) %>% st_sfc %>% data.frame(geom = ., NAME = as.character(1:length(.)), MAX_VALUE = 10, VALUE = 8, REGEN = 1) %>% st_sf() %>% st_buffer(1) %>% st_set_crs(32610), bounds = st_sfc(st_buffer(st_convex_hull(reduce(patches$geometry, c)), 1), crs = st_crs(patches)), foragers = createForagers(3, bounds = bounds, speed = 2, quiet = TRUE) )

Set default values for variables that are not entered manually

plotCurrent()

displays the current location of all foragers and patch geometries

plotPatches()

displays the current patch geometries

plotPaths()

displays the current location and path of all foragers as well as patch geometries

progress()

moves the entire environment forward one timestep by moving all foragers once and processing impact of foraging on patches

Examples

## Not run: 
Environment()
newForagers <- list(Forager(), Forager())
#foragers are created by default between -50 and 50 on both the x and y axis
newPatches <- lapply(rep(2, times = 20), function(x) st_point(runif(x, min = -50, max = 50)))
newPatches <- newPatches %>% st_sfc %>% data.frame(geom = ., NAME = as.character(1:length(.)))
newPatches <- newPatches %>% st_sf() %>% st_buffer(1)
newBounds <- st_sfc(st_convex_hull(reduce(newPatches$geometry, c)), crs = st_crs(newPatches))
Environment(newForagers, newPatches, newBounds)

## End(Not run)
