Plot confidence and prediction intervals for regression.

'plot.lmIntXY' 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 lmIntXY
plot(x, fit = FALSE, cia = FALSE, cif = FALSE, pi = FALSE,
    ...)

Arguments

x	an object of class 'lmIntXY'
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.)
...	additional arguments to be passed to the 'lines' function used to plot the lines

Note

deprecated, use 'lmInt' and 'plot.lmInt' instead
