Fit a base model to a species

Description

Fit a base model to a species

Usage

base_model(
  species = "Harm_axyr",
  min_occurrences = 1000,
  min_species = 3,
  first_order = TRUE,
  center_year = 2001
)

Arguments

species

Name of the species.

min_occurrences

The minimum number of occurrences per species.

min_species

The minimum number of species recorded at the combination of location and year.

first_order

Use first (TRUE) or second (FALSE) order random walk for the year component. Defaults to TRUE.

center_year

The year to center to. Defaults to 2001.


Fit a model to a species using the cumulative predictions for a secundary species

Description

Fit a model to a species using the cumulative predictions for a secundary species

Usage

cumulative_model(
  species = "Adal_bipu",
  min_occurrences = 1000,
  min_species = 3,
  secondary,
  first_order = TRUE,
  center_year = 2001
)

Arguments

species

Name of the species.

min_occurrences

The minimum number of occurrences per species.

min_species

The minimum number of species recorded at the combination of location and year.

secondary

The output of base_model() for a different species.

first_order

Use first (TRUE) or second (FALSE) order random walk for the year component. Defaults to TRUE.

center_year

The year to center to. Defaults to 2001.


Fit a model to a species using the predictions for a secondary species

Description

Fit a model to a species using the predictions for a secondary species

Usage

fit_model(first_order = TRUE, base_data, trend_prediction, base_prediction)

Arguments

first_order

Use first (TRUE) or second (FALSE) order random walk for the year component. Defaults to TRUE.

base_data

A dataframe with the base data.

trend_prediction

A dataframe with the timestamps to predict the trend.

base_prediction

A dataframe with the locations and timestamps to predict.


Import and standardise the raw data

Description

Import and standardise the raw data

Usage

import_data(belgium, output, strict = TRUE)

Arguments

belgium

path to the CSV file with the Belgian data.

output

path to the root of the data package

strict

What to do when the metadata changes. strict = FALSE overwrites the data and the metadata with a warning listing the changes, strict = TRUE returns an error and leaves the data and metadata as is. Defaults to TRUE.


Load the relevant occurrence data

Description

Load the relevant occurrence data

Usage

load_relevant(min_occurrences = 1000, min_species = 3)

Arguments

min_occurrences

The minimum number of occurrences per species.

min_species

The minimum number of species recorded at the combination of location and year.


Display a leaflet map with the occurrences for a given species

Description

Display a leaflet map with the occurrences for a given species

Usage

occurrence_map()

)

Arguments

Name of the species.

min_occurrences

The minimum number of occurrences per species.

min_species

The minimum number of species recorded at the combination of location and year.

secondary

The output of base_model() for a different species.

first_order
