expFit: Exponential Fit and plot of data

In MichaelJMahometa/OnRampsR2: Collection of functions for The University of Texas OnRamps Statistics course.

Description

Fit a exponential model to two variables, return basic output about the model, and plot the model.

Usage

expFit(simpleformula, data, xlab = NULL, ylab = NULL)

Arguments

simpleformula	a designation for the model formula in y ~ x notation. Must be in formula notation–see details.
data	a data frame in which to evaluate formulas.
xlab	optional. Text for x-axis title label for produced graph.
ylab	optional. Text for y-axis title label for produced graph.

Details

This function is one of a group of functions that take a specific input in the form of y ~ x, following (in-part) the mosaic package formula notation. However, only simple formulas are allowed with no grouping parameter, nor multiple predictor variables.
