bioconductor-treeio

'treeio' is an R package to make it easier to import and store phylogenetic tree with associated data; and to link external data from different sources to phylogeny. It also supports exporting phylogenetic tree with heterogeneous associated

treeio

Dependencies & Environment

Package-intrinsic requirements from the Bioconductor landing page — reproduce in any R environment.

  • Version: 1.36.1 · Bioconductor: 3.23 · R: ≥ 4.6
  • Imports: ape, dplyr, jsonlite, magrittr, rlang, tibble, tidytree, yulab.utils
  • Install: BiocManager::install("treeio")

When to Use

  • Phylogenetic Tree Input and Output: Managing phylogenetic tree data using the package's core base classes.
  • Vignette Redirection: Accessing the full documentation and tutorials by navigating to the external treedata-book resource linked in the package stub.

When NOT to Use

  • Detailed In-Package Tutorials: For comprehensive workflows, use the external treedata-book website because the built-in vignette is only a stub.
  • Tree Reconstruction: For inferring phylogenetic trees from sequence alignments, use external tools because treeio focuses strictly on base classes for input and output.

Data Requirements

  • Tree Files: Phylogenetic tree files compatible with the package's base classes for input and output.

Key Parameters

  • tidy (FALSE): knitr::opts_chunk$set option used to control code formatting in the vignette.
  • message (FALSE): knitr::opts_chunk$set option used to suppress messages during document compilation.

Best Practices

  • Consult External Documentation: Go to https://yulab-smu.top/treedata-book/ for the full vignette and comprehensive workflow instructions.
  • Clean Report Compilation: Set tidy = FALSE and message = FALSE in knitr::opts_chunk$set when compiling reports to avoid clutter.
  • Utilize Base Classes: Rely on the base classes provided by the package for consistent phylogenetic tree input and output.

Common Pitfalls

  • Missing Documentation: Looking for detailed tutorials in the standard vignette fails because it is only a stub. Fix: Go to the external treedata-book link provided in the vignette text.
  • Unwanted Compilation Messages: R outputs verbose messages during document rendering. Fix: Use message = FALSE in the knitr::opts_chunk$set options.

Alternatives

  • ape: Provides basic phylogenetic tree structures, but treeio offers specialized base classes for input and output.
  • phylobase: Another package for tree classes, but treeio is specifically designed for integration with the treedata-book ecosystem.
  • tidytree: Works alongside treeio for tidy data manipulation rather than just input/output.

The package contains functions for exploratory oligonucleotide array analysis. The dependence on tkWidgets only concerns few convenience functions. 'affy' is fully functional without it.

ASURAT is a software for single-cell data analysis. Using ASURAT, one can simultaneously perform unsupervised clustering and biological interpretation in terms of cell type, disease, biological process, and signaling pathway activity. Inputting a single-cell RNA-seq data and knowledge-based databases, such as Cell Ontology, Gene Ontology, KEGG, etc., ASURAT transforms gene expression tables into original multivariate tables, termed sign-by-sample matrices (SSMs).
