  deplete = TRUE)

Arguments

A vector of initial food items counts available to the organism in the environment

consumed

A vector of food items consumed by the organism

stand

Converts values with highest standardized to "1"? Defaults to FALSE.

For use in experiments where food sources deplete? Defaults to TRUE.

Examples

# NOT RUN {
initial_prey_count <- c(10,10,10,10,10,10)
number_prey_consumed <- c(9,8,1,3,5,9)
manlysalpha(initial = initial_prey_count, consumed = number_prey_consumed,
stand = TRUE, perc = FALSE, deplete = TRUE)

manlysalpha(initial = initial_prey_count, consumed = number_prey_consumed,
stand = TRUE, perc = TRUE, deplete = TRUE)

# }
