Arguments

`chronogram`	A chronogram either as a newick character string or as a 'phylo' object with branch length proportional to time.
`title`	A character string providing the title for the plot.
`time_depth`	A numeric vector indicating the upper limit for the time scale on the x axis.
`plot_type`	A character vector of length one indicating the type of plot to generate. Options are: "ape" It uses the functions [ape::plot.phylo()] and [ape::axisPhylo()]. "phyloch" It uses the functions [ape::plot.phylo()] and [phyloch::axisGeo()]. "strap" It uses the function [strap::geoscalePhylo()] from the package [strap]. "phytools" Not implemented yet. It will use functions from the package [phytools]
`time_axis`	Default to 'TRUE', add a time axis to the tree plot.
`mai1, mai2, mai3, mai4`	A numeric value indicating internal plot margin sizes in inches. 'mai4' is particularly important as it indicates the space needed for plotting whole tip labels on the right margin of the plot.
`omi1, omi2, omi3, omi4`	A numeric value indicating outter plot margin sizes in inches.
`plot_height, plot_width`	A numeric value indicating height and width for the plot.
`geologic_timescale`	A dataframe of geochronological limits.
`geologic_unit`	A character vector used to select geological time units that shall be displayed. When using `gradstein04`, `"eon"`, `"era"`, `"period"`, `"epoch"`, and `"stage"` are available.
`cex_tiplabels`	A numeric value indicating character expansion (i.e., size scaling factor) of tip labels in 'chronogram'. Default to value given by 'graphics::par("cex")'.
`cex_axislabel`	A numeric indicating character expansion for the time axis label. Default to value given by 'graphics::par("cex")'.
`cex_axis`	A numeric indicating character expansion for the axis. Default to value given by 'graphics::par("cex")'.
`cex_title`	A numeric indicating character expansion for the title. Default to value given by 'graphics::par("cex")'.
`pos_title`	Indicates the line position of the title. Default to 1.
`pos_axis`	Indicates the line position of the axis. Default to 1.
`center_axislabel`	A numeric indicating centering position of time axis label. Default to 0.5.
`axis_label`	A character string used to provide information on time units. Defaults to "Time (MYA)" (time in million years ago). If NULL, time units are not added.
`...`	Arguments passed on to `ape::plot.phylo` `x` an object of class `"phylo"` or of class `"multiPhylo"`. `type` a character string specifying the type of phylogeny to be drawn; it must be one of "phylogram" (the default), "cladogram", "fan", "unrooted", "radial", "tidy", or any unambiguous abbreviation of these. `use.edge.length` a logical indicating whether to use the edge lengths of the phylogeny to draw the branches (the default) or not (if `FALSE`). This option has no effect if the object of class `"phylo"` has no ‘edge.length’ element. `node.pos` a numeric taking the value 1 or 2 which specifies the vertical position of the nodes with respect to their descendants. If `NULL` (the default), then the value is determined in relation to ‘type’ and ‘use.edge.length’ (see details). `show.tip.label` a logical indicating whether to show the tip labels on the phylogeny (defaults to `TRUE`, i.e. the labels are shown). `show.node.label` a logical indicating whether to show the node labels on the phylogeny (defaults to `FALSE`, i.e. the labels are not shown). `edge.color` a vector of mode character giving the colours used to draw the branches of the plotted phylogeny. These are taken to be in the same order than the component `edge` of `phy`. If fewer colours are given than the length of `edge`, then the colours are recycled. `edge.width` a numeric vector giving the width of the branches of the plotted phylogeny. These are taken to be in the same order than the component `edge` of `phy`. If fewer widths are given than the length of `edge`, then these are recycled. `edge.lty` same as the previous argument but for line types; 1: plain, 2: dashed, 3: dotted, 4: dotdash, 5: longdash, 6: twodash. `node.color` a vector of mode character giving the colours used to draw the perpendicular lines associated with each node of the plotted phylogeny. These are taken to be in the same order than the component `node` of `phy`. If fewer colours are given than the length of `node`, then the colours are recycled. `node.width` as the previous argument, but for line widths. `node.lty` as the previous argument, but for line types; 1: plain, 2: dashed, 3: dotted, 4: dotdash, 5: longdash, 6: twodash. `font` an integer specifying the type of font for the labels: 1 (plain text), 2 (bold), 3 (italic, the default), or 4 (bold italic). `cex` a numeric value giving the factor scaling of the tip and node labels (Character EXpansion). The default is to take the current value from the graphical parameters. `adj` a numeric specifying the justification of the text strings of the labels: 0 (left-justification), 0.5 (centering), or 1 (right-justification). This option has no effect if `type = "unrooted"`. If `NULL` (the default) the value is set with respect of `direction` (see details). `srt` a numeric giving how much the labels are rotated in degrees (negative values are allowed resulting in clock-like rotation); the value has an effect respectively to the value of `direction` (see Examples). This option has no effect if `type = "unrooted"`. `no.margin` a logical. If `TRUE`, the margins are set to zero and the plot uses all the space of the device (note that this was the behaviour of `plot.phylo` up to version 0.2-1 of ‘ape’ with no way to modify it by the user, at least easily). `root.edge` a logical indicating whether to draw the root edge (defaults to FALSE); this has no effect if ‘use.edge.length = FALSE’ or if ‘type = "unrooted"’. `label.offset` a numeric giving the space between the nodes and the tips of the phylogeny and their corresponding labels. This option has no effect if `type = "unrooted"`. `underscore` a logical specifying whether the underscores in tip labels should be written as spaces (the default) or left as are (if `TRUE`). `x.lim` a numeric vector of length one or two giving the limit(s) of the x-axis. If `NULL`, this is computed with respect to various parameters such as the string lengths of the labels and the branch lengths. If a single value is given, this is taken as the upper limit. `y.lim` same than above for the y-axis. `direction` a character string specifying the direction of the tree. Four values are possible: "rightwards" (the default), "leftwards", "upwards", and "downwards". `lab4ut` (= labels for unrooted trees) a character string specifying the display of tip labels for unrooted trees (can be abbreviated): either `"horizontal"` where all labels are horizontal (the default if `type = "u"`), or `"axial"` where the labels are displayed in the axis of the corresponding terminal branches. This option has an effect if `type = "u"`, `"f"`, or `"r"`. `tip.color` the colours used for the tip labels, eventually recycled (see examples). `plot` a logical controlling whether to draw the tree. If `FALSE`, the graphical device is set as if the tree was plotted, and the coordinates are saved as well. `rotate.tree` for "fan", "unrooted", or "radial" trees: the rotation of the whole tree in degrees (negative values are accepted). `open.angle` if `type = "f"` or `"r"`, the angle in degrees left blank. Use a non-zero value if you want to call `axisPhylo` after the tree is plotted. `node.depth` an integer value (1 or 2) used if branch lengths are not used to plot the tree; 1: the node depths are proportional to the number of tips descending from each node (the default and was the only possibility previously), 2: they are evenly spaced. `align.tip.label` a logical value or an integer. If `TRUE`, the tips are aligned and dotted lines are drawn between the tips of the tree and the labels. If an integer, the tips are aligned and this gives the type of the lines (`lty`).
