fe_species_bavrn_state: Construct a _fe_species_bavrn_state_ Species Code Vector

In ForestElementsR: Data Structures and Functions for Working with Forest Data

Construct a fe_species_bavrn_state Species Code Vector

Description

User interface for constructing a vector of species codes follwing the fe_species_bavrn_state convention

Usage

fe_species_bavrn_state(x = character())

Arguments

x	Input vector to become a vector of tree species codes by the definition bavrn_state. Any type of vector (typically integer) which, after conversion with as.character, adheres to that definition is acceptable. If x is provided as a character vector, leading and trailing white spaces will be trimmed.

Details

The bavrn_state species coding is the species coding used by the Bavarian State Forest Service. See the example section for how to look up the coding.

Value

If the user input allows to construct a well-defined fe_species_bavrn_state object, this object will be returned. If not, the function will terminate with an error.

Examples

# Libraries required for the following two examples
library(dplyr)
library(purrr)

# Look up the bavrn_state species codes for all supported species
# the column species_id contains the bavrn_state codes
species_codings |>
  filter(species_coding == "bavrn_state") |>
  pluck(2, 1) |>
  arrange(as.numeric(species_id)) |> # just for the look of it
  print(n = Inf)

# Display a summary table which shows the number of single species behind
# each bavrn_state species code
species_codings |>
  filter(species_coding == "bavrn_state") |>
  pluck(2, 1) |>
  group_by(name_eng, species_id) |> # display english names
  summarise(n = n()) |>
  arrange(as.numeric(species_id)) |> # just for the look of it
  print(n = Inf)


# Make an fe_species_bavrn_state vector from a vector of integer codes
spec_ids <- fe_species_bavrn_state(
  c(10, 10, 10, 60, 60, 60, 60, 30, 30, 80, 86, 80)
)
