Create Quadratic Model — create_quad

A wrapper to create a quadratic model for curve data.

Usage

create_quad_model(
  curve_data,
  conc_var,
  signal_var,
  dilution_data = lifecycle::deprecated()
)

Arguments

curve_data: A data frame or tibble containing curve data.
conc_var: Column name in curve_data to indicate concentration.
signal_var: Column name in curve_data to indicate signal
dilution_data: dilution_data was renamed to curve_data.

Value

A linear model object from stats:lm() with formula signal_var ~ conc_var + I(conc_var * conc_var)

from data curve_data.

Examples

concentration <- c(10, 20, 40, 60, 80, 100)

signal <- c(22561, 31178, 39981, 48390, 52171, 53410)

curve_data <- data.frame(Concentration = concentration,
                         Signal = signal)

quad_model <- create_quad_model(
  curve_data,
  "Concentration",
  "Signal"
)
