Plot confidence and prediction intervals for regression.

'plot.lmInt' adds confidence and/or prediction intervals to an existing plot depicting a simple univariate linear model. The intervals are computed using the 'lmInt' function.

# S3 method for lmInt
plot(x, xx = colnames(x)[1], fit = FALSE, cia = FALSE,
    cif = FALSE, pi = FALSE, band = FALSE, ...)

Arguments

x	an object of class 'lmInt'
xx	the name of dependent variable to plot against
fit	plot the fitted regression line?
cia	plot confidence intervals around the regression line? (See 'lmInt' for explanation.)
cif	plot confidence intervals for the regression line? (See 'lmInt' for explanation.)
pi	plot prediction intervals? (See 'lmInt' for explanation.)
band	draw polygonal confidence bands instead of simple lines?
...	additional arguments to be passed to the 'lines' function used to plot the lines
