plotTree.Rd
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.

additional arguments for plotting. See
mia-plot-args
for more details i.e. call help("mia-plot-args")
a single character
value specifying a rowTree/colTree from
object
. (By default: tree_name = "phylo"
)
logical scalar, Should the tip labels be relabeled using
the output of getTaxonomyLabels(object, with_rank = TRUE)
?
(default: relabel_tree = FALSE
)
logical scalar, Should the tree be ordered based on
alphabetic order of taxonomic levels?
(default: order_tree = FALSE
)
logical scalar, Should taxonomic level information
be removed from labels? (default: relabel_tree = FALSE
)
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
)
logical scalar. Should legends be plotted?
(default: add_legend = TRUE
)
layout for the plotted tree. See
ggtree
for details.
Specification of a column metadata field or a feature
to colour tree edges by, see the by argument in
?retrieveCellInfo
for possible
values.
Specification of a column metadata field or a feature
to size tree edges by, see the by argument in
?retrieveCellInfo
for possible
values.
Specification of a column metadata field or a feature to
colour tree tips by, see the by argument in
?retrieveCellInfo
for possible
values.
Specification of a column metadata field or a feature to
shape tree tips by, see the by argument in
?retrieveCellInfo
for possible
values.
Specification of a column metadata field or a feature to
size tree tips by, see the by argument in
?retrieveCellInfo
for possible
values.
Specification of a column metadata field or a feature to
colour tree nodes by. Must be a field from other_fields
.
Specification of a column metadata field or a feature to
shape tree nodes by. Must be a field from other_fields
.
Specification of a column metadata field or a feature to
size tree nodes by. Must be a field from other_fields
.
Should the highlights be colour differently?
If show_highlights = TRUE
, colour_highlights
will be set to
TRUE
as default. (default: colour_highlights = FALSE
)
A string or integer scalar specifying which assay to
obtain expression values from, for use in point aesthetics - see the
exprs_values
argument in
?retrieveCellInfo
.
Additional fields to include in the node information without plotting them.
a ggtree
plot
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.
