tidy_taxonomy_tree: Assign (NCBI) taxonomy levels to phylo convertible tibble.
In cparsania/phyloR: Clean blast results for downstream phyloegentic analysis

Description Usage Arguments Value Examples

An object of class phylo can be converted to an object of class tibble and vice versa. The given function adds columns of ncbi taxonomy levels to the tibble created from class phylo. Resultant tibble can be passed to ggtree::ggtree() to visualize phylogenetic tree. Added taxonomy columns can be used for aesthetics such as tip color, node color etc.

tidy_taxonomy_tree(
  tree_data,
  ncbi_accession_colname = "ncbi_accession",
  taxonomy_levels = c("species", "kingdom")
)

`tree_data`	a tbl containing minimum columns required to create an object of class phylo.
`ncbi_accession_colname`	a string (default : "ncbi_accession") denoting column name of ncbi accession.
`taxonomy_levels`	a character vector containing levels of ncbi taxonomy. For each of these levels corresponding values will be mapped for ncbi accession.

a tbl containing all columns from tree_data + columns of assigned taxonomy levels.
