placer: A package to estimate the accumulation of plastic debris in bird's nests

Description

The package placer consist of two main functions to estimate the accumulation of plastic in bird's nest as a function of sample size, and a routine to plot the plastic prevalence probability, and their confidence intervals as a function of sample size.

Main functions

The function plastic.prev.prob calculates the plastic prevalence probability for a given sample size based on presence and absence data The function plastic.ci estimates the 95% confidence intervals for a given prevalence probability of plastic debris. In addition, the package placer includes a plotting routine prevalence_plot to show the estimated plastic prevalence probability and their 95% confidence intervals as a function of sample size.
