Pollen - tools for working with aerobiological data

<!--[![Coverage Status](https://img.shields.io/codecov/c/github/hadley/lubridate/master.svg)](https://codecov.io/github/hadley/lubridate?branch=master)-->

The pollen package is a set of functions for working with aerobiological data. It takes care of some of the most widely use aerobiological calculations, including determination of pollen season limits, replacement of outliers (Kasprzyk and Walanus (2014)), and calculation of growing degree days (Baskerville and Emin (1969)).

Installation

Get the released version from CRAN:

install.packages("pollen")

Or the development version from github:

remotes::install_github("nowosad/pollen")

Examples

library(pollen)

data("pollen_count")
head(pollen_count)

Pollen season calculation

df <- subset(pollen_count, site == "Oz")
pollen_season(value = df$birch, date = df$date, method = "95")

More examples of pollen seasons' calculations can be found in the first package vignette.

Growing degree days (GDD) calculation

Examples of Growing degree days (GDD) calculations can be found in the second package vignette.
