The size of nodes, edges, labels, and trees can be mapped to arbitrary numbers.
This is useful for displaying statistics for taxa, such as abundance.
Only the relative size of numbers is used, not the values themeselves.
They can be transformed to make the mapping non-linear using the transformation options.
The range of actual sizes displayed on the graph can be set using the range options. Accepts a numeric vector, the same length taxon_id or a
factor of its length.colors
The colors of nodes, edges, labels, and trees can be mapped to arbitrary numbers.
This is useful for highlighting groups of taxa.
Only the relative size of numbers is used, not the values themeselves.
They can be transformed to make the mapping non-linear using the transformation options.
The range of actual colors displayed on the graph can be set using the range options. Accepts a vector, the same length taxon_id or a factor of its length.
If a numeric vector is given, it is mapped to a color scale.
Hex values or color names can be used (e.g. #000000 or "black").labels
The labels of nodes, edges, and trees can be added.
Node labels are centered over their node.
Edge labels are displayed over edges, in the same orientation.
Tree labels are displayed over their tree. Accepts a vector, the same length taxon_id or a factor of its length.transformations
Before any numbers specified are mapped to color/size, they can be transformed to make
the mapping non-linear.
Any of the transformations listed below can be used by specifying their name.
A customized function can also be supplied to do the transformation.
ranges
The displayed range of colors and sizes can be explicitly defined or automatically genereated.
Size ranges are specified by supplying a numeric vector with two values: the minimum and maximum.
The units used should be between 0 and 1, representing the proportion of a dimension of the graph.
Since the dimensions of the graph are determined by layout, and not always square, the value
that 1 corresponds to is the square root of the graph area (i.e. the side of a square with
the same area as the plotted space).
Color ranges can be any number of color values as either HEX codes (e.g. #000000) or
color names (e.g. "black").layout
Layouts determine the position of nodes on the graph.
The are implemented using the igraph package.
Any additional arguments passed to heat_tree are passed to the igraph
function used.
The following character values are understood:
intervals
This is the minimum and maximum of values displayed on the legend scales.
Intervals are specified by supplying a numeric vector with two values: the minimum and maximum.
These are defined in the same units as element size/color.
By default, the minimum and maximum equals the range of the values used to infer size/color.
Setting a custom interval is useful for making size/color in multiple graphs correspond to the same statistics,
or setting logical bounderies (such as c(0,1) for proportions.
Note that this is different from the "range" options, which determine the range of graphed sizes/colors.
