Quantify geographic sampling bias with {sampbias}

Eukaryota
Animalia
Chordata
Summaries

Human biases play a large role in the data we collect about species. Here we show a simple method to quantify the bias of roads, cities, rivers and airports on species observations of legless lizards in the Northern Territory

Multiple colour scales in choropleth maps with {ggnewscale}

Eukaryota
Plantae

Maps

Using multiple colour scales can be a great way to visually differentiate between geographic categories on a map. Here, we demonstrate this by creating a choropleth map to represent the density of plant records from the ALA across bioregions in Australia, and add multiple colour scales to differentiate marine and terrestrial records

Download plant species data by hexagon to make a 3D hex map

Making plots eye-catching can be useful for science communication. Here, we show how to make 3D plots in R with the `rayshader` package by visualising the number of species identified from ALA observations since 2020

Hex maps for species occurrence data

Maps
Eukaryota
Animalia
Chordata

Hex maps are a neat way to represent spatial information. Here, we show how to draw one using the most common species in the ALA database: the iconic Australian Magpie.

Sunburst plots for taxonomic data

Trees
Eukaryota

Chordata

Since version 1.3.1 of `galah`, it has been possible to download taxonomic data using a 'tree' format from the `data.tree` package. Here I'll demonstrate some ideas for plotting these trees using circular diagrams.

Creating a color palette from an image

Summaries
Eukaryota
Plantae

There are hundreds of color palettes in the R ecosystem, but sometimes we might want to use colors from a specific image. Here I show how to use the `paletter` package to create a color palette for the 2020 Eucalypt of the Year: the Western Australian Gimlet.
