View source: R/generate_preds_and_encs.R
Description
Probability that prey encounters a predator in each cell
based on the idea that each predator will engage prey within a certain radius
total area occupied by predators divided by cell area is the encounter probability
Usage
1
calc_enc_probs(df, grid_size = 15, reaction_dis = 0.5)
Arguments
df
dataframe of predator counts per cell; use output from create_stream_raster_frame function
grid_size
length of side of raster grid in meters; default is 15
reaction_dis
maximum distance (in m) away from a predator that can trigger an encounter; default is 0.50
Value
a dataframe of encounter probabilities per grid cell for the entire reach
Examples
1
2
3
pred_pos <- get_pred_positions()
raster <- create_stream_raster_frame(pred_pos)
calc_enc_probs(raster)
