expFitPred: Exponential Fit and plot of data with a predicted value

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

Description

Show where a given predicted value will occur, give an input of x (exponential models).

Usage

expFitPred(
  simpleformula,
  data,
  xval,
  xlab = NULL,
  ylab = NULL,
  newxlim = NULL,
  newylim = NULL,
  showpred = TRUE
)

Arguments

simpleformula	a designation for the model formula in y ~ x notation. Must be in formula notation–see details.
xval	a value of x that you wish to see a predicted value for.
xlab	optional. Text for x-axis title label.
ylab	optional. Text for y-axis title label.
newxlim	optional. Custom limits for the x axis.
newylim	optional. Custom limits for the y axis.
showpred	logical. Should the predicted point value be plotted on the graph?
