| plotCI.reg {asbio} | R Documentation |
Plots a simple linear regression along with confidence and prediction intervals.
Description
Plots the fitted line from a simple linear regression (y ~ x) and (if requested) confidence and prediction intervals.
Usage
plotCI.reg(x, y, conf = 0.95, CI = TRUE, PI = TRUE, resid = FALSE, reg.col = 1,
CI.col = 2, PI.col = 4, reg.lty = 1, CI.lty = 2, PI.lty = 3, reg.lwd = 1,
CI.lwd = 1, resid.lty = 3, resid.col = 4,...)
Arguments
