Description

Creates an interactive Q-Q plot with multiple annotation options

Usage

qqly(
  x,
  ...,
  col = "#252525",
  size = 5,
  type = 20,
  abline_col = "red",
  abline_size = 1,
  abline_type = "solid",
  highlight = NULL,
  highlight_color = "#00FF00",
  xlab = "Expected -log10(p)",
  ylab = "Observed -log10(p)",
  title = "Q-Q Plot"
)

Arguments

x

Can be an object of class qqr produced by the qqr function or a data.frame which must contain at least the following column:

• a p-value, must be numeric

...

other parameters passed to qqr

col

A character indicating the color of the points. Can be Hex Codes as well.

size

A numeric specifying the size of the points. Default is 1

type

An integer between 0 and 25 specifying the point shape. Default is 20 (filled circle). Deprecated.

abline_col

A character indicating the color of the 45 degree diagonal line. Can be Hex Codes as well. Default is "red".
