Make Krona files using KronaTools.

Need the installation of kronatools on the computer (installation instruction).

Usage

  file = "krona.html",
  nb_seq = TRUE,
  ranks = "All",
  add_unassigned_rank = 0,
  name = NULL
)

Arguments

physeq

(required): a phyloseq-class object obtained using the phyloseq package.

file

(required) the location of the html file to save

nb_seq

(logical) If true, Krona set the distribution of sequences in the taxonomy. If False, Krona set the distribution of ASVs in the taxonomy.

ranks
