Interpolate Richness at Target Coverage Levels

Estimate species richness at specified coverage levels by interpolation.

Usage

interpolateCoverage(x, target = c(0.9, 0.95, 0.99))

Arguments

x

A spacc_coverage object.

target

Numeric vector of target coverage levels (0 to 1). Default c(0.90, 0.95, 0.99).

Value

A data.frame with columns for each target coverage level, showing interpolated richness for each seed.
