sPMMA: syndiotactic poly-methyl-methacrylate

In NRAIA: Data sets from "Nonlinear Regression Analysis and Its Applications"

Description

The sPMMA data frame has 23 rows and 3 columns from an experiment on the dielectric response of a sample of syndiotactic poly-methyl-methacrylate (sPMMA).

Format

This data frame contains the following columns:

freq

a numeric vector giving the frequency of the driving signal (Hz).

real

a numeric vector giving the real component of the dielectric response.

imag

a numeric vector giving the imaginary component of the dielectric response.

Examples

str(sPMMA)
xyplot(imag ~ real, data = sPMMA, xlab = "Real component",
     ylab = "Imaginary component", type = c("p", "g"))
xyplot(real + imag ~ freq, data = sPMMA, xlab = "Frequency (Hz)",
     ylab = "Component of dielectric response",
     main = "sPMMA data", type = c("g", "p"), aspect = 'xy',
     auto.key = list(space = "right"))
