Compute Functional Diversity Using All Dissimilarities

Description

Compute Functional Diversity Using All Dissimilarities

Usage

compute_dissim_di(trait_dissim_list, site_sp_df, trait_comb_df)

Arguments

trait_dissim_list	[⁠list(list(matrix(1+)))⁠] a list containing list of dissimilarity matrices with their names
site_sp_df	[data.frame()] a tidy species data.frame with a row defining a species in a site with its abundance
trait_comb_df	[data.frame()] a data.frame with the list of trait combinations considered as well as the number of traits included

---

Compute FD indices without abundances

Description

Wrapper around FD::dbFD()

Usage

compute_other_fd(site_sp_df, trait_comb, trait_df, var_type = "env")

Arguments

site_sp_df	[data.frame()] a tidy species data.frame with a row defining a species in a site with its abundance
trait_comb	[⁠list(character(1+))⁠] a list contaning combinations of trait combinations
trait_df	[data.frame()] a trait data.frame with species as rows and traits as columns
var_type	[character(1)] a string giving the column on which site_sp_df should be spread

---

Compute Trait Dissimilarities

Description

For each provided trait combination in a list, returns a list of dissimilarity matrices computed using funrar. This function computes euclidean dissimilarity matrices

Usage

compute_trait_dissim(trait_comb_list, trait_df)

Arguments

trait_comb_list	[⁠list(character(1+))⁠] a list of character vectors containing the trait combination on which dissimilarity should be computed
trait_df	[data.frame()] a trait data.frame with species as rows and traits as columns

Value

a list of dissimilarity matrices with concatenated names from trait combinations

---

Generate uncorrelated traits

Description

Generate uncorrelated traits

Usage

generate_traits(n_species, n_traits)

Arguments

n_species	[integer(1)] the number of species
n_traits	[integer(1)] the number of traits

Value

a matrix with n_species rows and n_traits column with uniform uncorrelated traits between 0 and 1

Examples

generate_traits(3, 2)

Description

Contains Local vs. Global drake workflow

Usage

global_workflow()

---

Figure of FD vs. Environment Comparing Observed and SES values

Description

Figure of FD vs. Environment Comparing Observed and SES values

Usage

plot_env_fd_obs_ses_two(full_fd_df)

Arguments

full_fd_df

[data.frame()] data.frame containing both observed and SES values of functional diversity
