Permutational Multivariate Analysis of Variance Using Distance Matrices for MPSE or tbl_mpse object

Description

Permutational Multivariate Analysis of Variance Using Distance Matrices for MPSE or tbl_mpse object

Usage

mp_adonis(
  .data,
  .abundance,
  .formula,
  distmethod = "bray",
  action = "get",
  permutations = 999,
  seed = 123,
  ...
)

## S4 method for signature 'MPSE'
mp_adonis(
  .data,
  .abundance,
  .formula,
  distmethod = "bray",
  action = "get",
  permutations = 999,
  seed = 123,
  ...
)

## S4 method for signature 'tbl_mpse'
mp_adonis(
  .data,
  .abundance,
  .formula,
  distmethod = "bray",
  action = "get",
  permutations = 999,
  seed = 123,
  ...
)

## S4 method for signature 'grouped_df_mpse'
mp_adonis(
  .data,
  .abundance,
  .formula,
  distmethod = "bray",
  action = "get",
  permutations = 999,
  seed = 123,
  ...
)

Arguments

.data	MPSE or tbl_mpse object
.abundance	the name of abundance to be calculated.
.formula	Model formula right hand side gives the continuous variables or factors, and keep left empty, such as ~ group, it is required.
distmethod	character the method to calculate pairwise distances, default is 'bray'.
action	character "add" joins the cca result to the object, "only" return a non-redundant tibble with the cca result. "get" return 'cca' object can be analyzed using the related vegan funtion.
permutations	the number of permutations required, default is 999.
seed	a random seed to make the adonis analysis reproducible, default is 123.
...	additional parameters see also 'adonis2' of vegan.

Value

update object according action argument

Examples

data(mouse.time.mpse)
mouse.time.mpse %>%
  mp_decostand(
     .abundance=Abundance, 
     method="hellinger") %>%
  mp_adonis(.abundance=hellinger, 
            .formula=~time, 
            distmethod="bray", 
            permutations=999, # for more robust, set it to 9999. 
            action="get")
