Arguments

x	Numeric vector: Input values, e.g. log2 fold change, coefficients, etc.
pvals	Numeric vector: p-values
xnames	Character vector: x names
group	Factor: Used to color code points. If NULL, significant points below x.thresh, non-significant points, and significant points above x.thresh will be plotted with the first, second and third color fo palette
x.thresh	Numeric x-axis threshold separating low from high
p.thresh	Numeric: p-value threshold of significance. Default = .05
p.transform	function. Default = ⁠\(x) -log10(x)⁠
p.adjust.method	Character: p-value adjustment method. "holm", "hochberg", "hommel", "bonferroni", "BH", "BY", "fdr", "none" Default = "holm". Use "none" for raw p-values.
legend	Logical: If TRUE, show legend. Will default to FALSE, if group = NULL, otherwise to TRUE
legend.lo	Character: Legend to annotate significant points below the x.thresh
legend.hi	Character: Legend to annotate significant points above the x.thresh
label.lo	Character: label for low values
label.hi	Character: label for high values
main	Character: Main plot title.
xlab	Character: x-axis label
ylab	Character: y-axis label
margin	Named list of plot margins. Default = list(b = 65, l = 65, t = 50, r = 10, pad = 0)
xlim	Numeric vector, length 2: x-axis limits
ylim	Numeric vector, length 2: y-axis limits
alpha	Numeric: point transparency
hline	Numeric: If defined, draw a horizontal line at this y value.
hline.col	Color for hline. Default = "#ff0000" (red)
hline.width	Numeric: Width for hline. Default = 1
hline.dash	Character: Type of line to draw: "solid", "dot", "dash", "longdash", "dashdot", or "longdashdot"
hline.annotate	Character: Text of horizontal line annotation if hline is set
hline.annotation.x	Numeric: x position to place annotation with paper as reference. 0: to the left of the plot area; 1: to the right of the plot area
annotate	Logical: If TRUE, annotate significant points
annotate.col	Color for annotations
theme	List or Character: Either the output of a ⁠theme_*()⁠ function or the name of a theme. Use themes() to get available theme names. Theme functions are of the form ⁠theme_<name>⁠.
font.size	Float: Font size for all labels. Default = 16
palette	Character: Name of rtemis palette to use. Default = "rtCol1". Only used if col = NULL
legend.x.lo	Numeric: x position of legend.lo
legend.x.hi	Numeric: x position of legend.hi
legend.y	Numeric: y position for legend.lo and legend.hi
annotate.n	Integer: Number of significant points to annotate
ax.lo	Numeric: Sets the x component of the arrow tail about the arrow head for significant points below x.thresh
ay.lo	Numeric: Sets the y component of the arrow tail about the arrow head for significant points below x.thresh
ax.hi	Numeric: Sets the x component of the arrow tail about the arrow head for significant points above x.thresh
ay.hi	Numeric: Sets the y component of the arrow tail about the arrow head for significant points above x.thresh
annotate.alpha	Numeric: Transparency for annotations
hovertext	List of character vectors with hovertext to include for each group of markers
displayModeBar	Logical: If TRUE, show plotly's modebar
filename	Character: Path to file to save static plot. Default = NULL
file.width	Integer: File width in pixels for when filename is set.
file.height	Integer: File height in pixels for when filename is set.
file.scale	Numeric: If saving to file, scale plot by this number
verbose	Logical: If TRUE, print messages to console
...	Additional parameters passed to dplot3_xy
