rf_clf.comps

Description

It runs standard random forests with oob estimation for classification of one level VS all other levels of one category in the datasets. The output includes a list of rf models for the sub datasets and all important statistics for each of features.

Usage

rf_clf.comps(
  df,
  f,
  comp_group,
  verbose = FALSE,
  clr_transform = TRUE,
  rf_imp_values = FALSE,
  ntree = 500,
  p.adj.method = "bonferroni",
  q_cutoff = 0.05
)

Arguments

df	Training data: a data.frame.
f	A factor in the metadata with at least two levels (groups).
comp_group	A string indicates the group in the f
verbose	A boolean value indicating if show computation status and estimated runtime.
clr_transform	A boolean value indicating if the clr-transformation applied.
rf_imp_values	A boolean value indicating if compute both importance score and pvalue for each feature.
ntree	The number of trees.
p.adj.method	The p-value correction method, default is "bonferroni".
q_cutoff	The cutoff of q values for features, the default value is 0.05.
