Filter traits with a given species coverage threshold — fb_filter_traits_by_species_coverage • funbiogeo

Selects traits (columns) for which the percentage of species without NA (missing trait values) is higher than a threshold.

Usage

fb_filter_traits_by_species_coverage(
  species_traits,
  threshold_species_proportion = 0
)

Arguments

species_traits: a data.frame with species in rows and traits as columns. NOTE: The first column should be named "species" and contain species names. The other columns should be named according to trait names.
threshold_species_proportion: numeric(1) [default = NULL]
between 0 and 1. The percentage of species coverage threshold.

Value

A subset of species_traits with traits for the specified proportion of species.

Examples

library("funbiogeo")

data("species_traits")

# Filter traits that have at least 60% non-missing values
new_species_traits <- fb_filter_traits_by_species_coverage(
  species_traits,
  threshold_species_proportion = 0.6
)

# There are now only 2 traits
ncol(new_species_traits)
#> [1] 3
