ggnostic residuals

If non-null pVal and sigma values are given, confidence interval lines will be added to the plot at the specified pVal percentiles of a N(0, sigma) distribution.

ggally_nostic_resid(
  data,
  mapping,
  ...,
  linePosition = 0,
  lineColor = brew_colors("grey"),
  lineSize = 0.5,
  lineAlpha = 1,
  lineType = 1,
  lineConfColor = brew_colors("grey"),
  lineConfSize = lineSize,
  lineConfAlpha = lineAlpha,
  lineConfType = 2,
  pVal = c(0.025, 0.975),
  sigma = attr(data, "broom_glance")$sigma,
  se = TRUE,
  method = "auto",
  formula = y ~ x
)
