calc_C_target {mobr} | R Documentation |
Calculate the recommended target coverage value for the computation of beta_C
Description
Returns the estimated gamma-scale coverage that corresponds to the largest allowable sample size (i.e. the smallest observed sample size at the alpha scale multiplied by an extrapolation factor). The default (factor = 2) allows for extrapolation up to 2 times the observed sample size of the smallest alpha sample. For factor= 1, only interpolation is applied. Factors larger than 2 are not recommended.
Usage
calc_C_target(x, factor = 2)
Arguments
x |
a site by species abundance matrix |
factor |
numeric. A multiplier for how much larger than total community abundance to extrapolate to. Defaults to 2. |
Value
numeric value
Examples
data(tank_comm)
