mixedFontLabel: Mixed Font Labels for Plotting

Description

This function helps to format labels with bits of text in different font shapes (italics, bold, or bolditalics) and different separators. The output is intended to be used for plotting.

Usage

mixedFontLabel(..., sep = " ", italic = NULL, bold = NULL,
               parenthesis = NULL,
               always.upright = c("sp.", "spp.", "ssp."))

Arguments

Value

A vector of mode expression.

Details

The idea is to have different bits of text in different vectors that are put together to make a vector of Rexpressions. This vector is interpreted by graphical functions to format the text. A simple use may be mixedFontLabel(genus, species), italic = 1:2, but it is more interesting when mixing fonts (see examples).

To have an element in bolditalics, its number must given in both italic and bold.

The vector returned by this function may be assigned as the tip.label element of a tree of class "phylo", or even as its node.label element.

Examples

Run this code
tr <- read.tree(text = "((a,(b,c)),d);")
genus <- c("Gorilla", "Pan", "Homo", "Pongo")
species <- c("gorilla", "spp.", "sapiens", "pygmaeus")
geo <- c("Africa", "Africa", "World", "Asia")
tr$tip.label <- mixedFontLabel(genus, species, geo, italic = 1:2,
  parenthesis = 3)
layout(matrix(c(1, 2), 2))
plot(tr)
tr$tip.label <- mixedFontLabel(genus, species, geo, sep = c("", "| "),
  italic = 1:2, bold = 3)
plot(tr)
layout(1)
