Creates a scatterplot with a common horizontal axis and two different variables plotted on the vertical axis with regression lines

Description

Creates a scatterplot with a common horizontal axis and two different variables plotted on the vertical axis with regression lines

Usage

chem_dual.scatter(data, xvar, yvar1, yvar2, xlab = "Insert X-axis label",
  ylab = "Insert Y-axis label", intercept1 = NULL, intercept2 = NULL,
  size = 3, colors = c("red", "blue"))

Arguments

data	A data frame containing variables to be plotted
xvar	The name of the x-variable
yvar1	The name of one of the y-variables
yvar2	The name of the other y-variable
xlab	A string containing the x-axis label
ylab	A string containing the y-axis label
intercept1	Set to NULL by default, but can be changed to 0 to force regression line to go through origin for yvar1
intercept2	Set to NULL by default, but can be changed to 0 to force regression line to go through origin for yvar2
size	A numeric specifying the size of the points
colors	A character vector specifying colors of two y-variables and each line

Value

A plot
