Analysis of Multi Response Permutation Procedure (MRPP) with MPSE or tbl_mpse object

Description

Analysis of Multi Response Permutation Procedure (MRPP) with MPSE or tbl_mpse object

Usage

mp_mrpp(
  .data,
  .abundance,
  .group,
  distmethod = "bray",
  action = "add",
  permutations = 999,
  seed = 123,
  ...
)

## S4 method for signature 'MPSE'
mp_mrpp(
  .data,
  .abundance,
  .group,
  distmethod = "bray",
  action = "add",
  permutations = 999,
  seed = 123,
  ...
)

## S4 method for signature 'tbl_mpse'
mp_mrpp(
  .data,
  .abundance,
  .group,
  distmethod = "bray",
  action = "add",
  permutations = 999,
  seed = 123,
  ...
)

## S4 method for signature 'grouped_df_mpse'
mp_mrpp(
  .data,
  .abundance,
  .group,
  distmethod = "bray",
  action = "add",
  permutations = 999,
  seed = 123,
  ...
)

Arguments

.data	MPSE or tbl_mpse object
.abundance	the name of abundance to be calculated.
.group	The name of the column of the sample group information.
distmethod	character the method to calculate pairwise distances, default is 'bray'.
action	character "add" joins the ANOSIM result to internal attribute of the object, "only" return a tibble contained the statistic information of MRPP analysis, and "get" return 'mrpp' 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 MRPP analysis reproducible, default is 123.
...	additional parameters see also 'mrpp' of vegan.

Value

update object according action argument

Examples

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