lb {renz}

Lineweaver-Burk Transformation

Description

Obtains Km and Vm using double reciprocal transformation

Usage

lb(data, unit_S = 'mM', unit_v = 'au', weighting = FALSE, plot = TRUE)

Arguments

data

a dataframe where the first column is the independent variable, [S], and the remaining columns (as many as experiment replicates) correspond to the dependent variable, v.

unit_S

concentration unit.

unit_v

time unit.

weighting

logical. When TRUE the weight v^4 is employed.

plot

logical. If TRUE the data and fitted line are plotted.

Value

A double reciprocal plot and the Km and Vm computed using averaged 1/v (when more than one replicate is provided). In addition, this function returns a list of five elements. The first and second ones are vectors with the Km and Vm, respectively, computed individually for each replicate. The third one provides the R-squared values of the fits. The fourth element of the list gives the fitted Km and Vm. The last element of the list is a dataframe with the values of the transformed variables.
