Dose-response curve

Source: R/geoms-clinical.R

A four-parameter log-logistic curve fitted to dose-response data, with a confidence band and the fitted EC50 marked.

geom_dose_response(
  mapping = NULL,
  data = NULL,
  color = NULL,
  points = TRUE,
  ec50 = TRUE
)

Arguments

mapping, data

Standard layer overrides. Map dose to x and response to y.

color

Curve color.

points

Draw the observed points.

ec50

Mark the fitted EC50 with a vertical line.

Value

A Layer to add with +.

Examples

d <- data.frame(
  dose = rep(c(0.1, 1, 10, 100, 1000), each = 3),
  resp = c(5, 7, 6, 18, 22, 20, 52, 48, 55, 82, 79, 85, 95, 97, 93)
)
ggnext(d, aes(dose, resp)) + geom_dose_response() + scale_x_log10()
