Usage

ewaff.qq.plot(
  p.values,
  sig.threshold = 1e-07,
  sig.color = "red",
  title = "QQ plot",
  xlab = bquote(-log[10]("expected p-values")),
  ylab = bquote(-log[10]("observed p-values")),
  lambda.method = "median"
)

title	Title for the plot (Default: "QQ plot").
xlab	Label for the x-axis (Default: -log_10(expected p-values)).
ylab	Label for the y-axis (Default: -log_10(observed p-values)).
lambda.method	Method for calculating genomic inflation lambda. Valid values are "median", "regression", "robust", or "none" (Default: "median"). A value of "none" will prevent the lambda value being displayed on the plot.
