dir.MM {renz}

Non-linear Least-squares Fitting of the MM equation

Description

Non-linear least-squares fitting of the Michaelis-Menten equation.

Usage

dir.MM(data, unit_S = 'mM', unit_v = 'au', plot = TRUE)

Arguments

data

a dataframe with two columns. The first column contains the values of the independent variable (substrate concentration), and the second column contains the initial rates.

unit_S

concentration unit.

unit_v

time unit.

plot

logical. If true, the data and fitted curve are plotted.

Details

This function invokes nls() to carry out the fitting.

Value

A list of two elements. The first one is a vector containing the enzyme kinetic parameters. The second one is a dataframe with the original data plus the fitted value of v.

Examples

dir.MM(ONPG[, c(1,2)])
