Plot Silica Concentrations vs. Absorbance
Description
This function plots the Standard Calibration curves from known concentration of silica in standard solutions against absorbance values from spectrophotometer analysis. It takes Silica concentration values as Y argument and their absorbance values from spectrophotometer as X argument then creates a scatter plot, fits a line of best fit, and returns the y-intercept and R-squared values.
Usage
plotStdC(
concentration,
absorbance,
title = "Concentration vs. Absorbance",
xlab = "Absorbance",
ylab = "Concentration (Millimoles)"
)
Arguments
concentration |
A numeric vector of concentration values. |
absorbance |
A numeric vector of absorbance values. |
title |
A character string for the plot title. |
xlab |
A character string for the x-axis label. |
ylab |
A character string for the y-axis label. |
Value
A list with components:
intercept: The y-intercept of the fitted line.
rsquared: The R-squared value of the fitted line.
equation : The equation of the fitted line in the form y=mx+C
Examples
concentration <- c(1, 2, 3, 4, 5)
absorbance <- c(0.1, 0.3, 0.6, 0.8, 1.2)
plotStdC(concentration, absorbance,
title = "Concentration vs. Absorbance",
xlab = "Absorbance",
ylab = "Concentrations")
