Based on the stored data in a TreeSummarizedExperiment a tree can be plotted. From the rowData, the assays as well as the colData information can be taken for enriching the tree plots with additional information.

Arguments

x

a TreeSummarizedExperiment.

...

additional arguments for plotting. See mia-plot-args for more details i.e. call help("mia-plot-args")

tree.name

Character scalar. Specifies a rowTree/colTree from x. (Default: tree.name = "phylo")

tree_name

Deprecated. Use tree.name instead.

relabel.tree

Logical scalar. Should the tip labels be relabeled using the output of getTaxonomyLabels(x, with_rank = TRUE)? (Default: FALSE)

relabel_tree

Deprecated. Use relavel.tree instead.

order.tree

Logical scalar. Should the tree be ordered based on alphabetic order of taxonomic levels? (Default: FALSE)

order_tree

Deprecated. Use order.tree instead.

levels.rm

Logical scalar. Should taxonomic level information be removed from labels? (Default: FALSE)

remove_levels

Deprecated. Use levels.rm instead.

show.label, show.highlights, show.highlight.label, abbr.label

logical (scalar), integer or character vector. If a logical scalar is given, should tip labels be plotted or if a logical vector is provided, which labels should be shown? If an integer or character vector is provided, it will be converted to a logical vector. The integer values must be in the range of 1 and number of nodes, whereas the values of a character vector must match values of the label column in the node data. In case of a character vector only values corresponding to actual labels will be plotted and if no labels are provided no labels will be shown. (Default: FALSE)

show_label, show_highlights, show_highlight_label, abbr_label

Deprecated. Use show.label, show.highlights, show.highlight.label, abbr_label instead.

add.legend

Logical scalar. Should legends be plotted? (Default: TRUE)

add_legend

Deprecated. Use add.legend instead.

layout

layout for the plotted tree. See ggtree for details.

edge.colour.by

Character scalar. Specification of a column metadata field or a feature to colour tree edges by, see the by argument in ?retrieveCellInfo for possible values.

edge_colour_by

Deprecated. Use edge.colour.by instead.

edge.size.by

Character scalar. Specification of a column metadata field or a feature to size tree edges by, see the by argument in ?retrieveCellInfo for possible values. (Default: NULL)

edge_size_by

Deprecated. Use edge.size.by instead.

tip.colour.by

Character scalar. Specification of a column metadata field or a feature to colour tree tips by, see the by argument in ?retrieveCellInfo for possible values. (Default: NULL)

tip_colour_by

Deprecated. Use tip.colour.by instead.

tip.shape.by

Character scalar. Specification of a column metadata field or a feature to shape tree tips by, see the by argument in ?retrieveCellInfo for possible values. (Default: NULL)

tip_shape_by

Deprecated. Use tip.shape.by isntead.

tip.size.by

Character scalar. Specification of a column metadata field or a feature to size tree tips by, see the by argument in ?retrieveCellInfo for possible values. (Default: NULL)

tip_size_by

Deprecated. Use tip.size.by instead.

node.colour.by

Character scalar. Specification of a column metadata field or a feature to colour tree nodes by. Must be a field from other.fields. (Default: NULL)

node_colour_by

Deprecated. Use node.colour.by instead.

node.shape.by

Character scalar. Specification of a column metadata field or a feature to shape tree nodes by. Must be a field from other.fields. (Default: NULL)

node_shape_by

Deprecated. Use node.shape.by instead.

node.size.by

Character scalar. Specification of a column metadata field or a feature to size tree nodes by. Must be a field from other.fields. (Default: NULL)

node_size_by

Deprecated. Use node.size.by instead.

colour.highlights.by

Logical scalar. Should the highlights be colour differently? If show.highlights = TRUE, colour_highlights will be set to TRUE as default. (Default: FALSE)

colour_highlights_by

Deprecated. Use colour.highlights.by instead.

assay.type

Character scalar. or integer scalar. Specifies which assay to obtain expression values from, for use in point aesthetics - see the exprs_values argument in ?retrieveCellInfo. (Default: "counts")

by_exprs_values

Deprecated. Use assay.type instead.

other.fields

Character vector. Additional fields to include in the node information without plotting them. (Default: list())

other_fields

Deprecated. Use other.fields instead.

Value

a ggtree plot

Details

If show.label or show.highlight.label have the same length as the number of nodes, the vector will be used to relabel the nodes.
