Compute Region of Positive Fitnes — viable

Compute region of positive fitness. This will be the values where fitness is approximately zero.

viable_fitness(bounds, p, x = NULL, log_scale = TRUE, dx = 1)

Arguments

bounds	Matrix of bounds; two columns corresponding to the lower and upper limits, each row corresponds to a trait (the name will be used).
p	Parameters object to use. Importantly, the `strategy_default` element gets used here.
x	Initial value - If not given, then the value from the default strategy within `p` is used.
log_scale	Is the parameter naturally on a log scale? If so, this will greatly speed things up. Can be a vector of length ``nrow(bounds)``
dx	Amount to step the trait. If `log_scale` is `TRUE`, this is on a log scale.
