R: Add Straight Lines to a Plot

The coef form specifies the line by a vector containing the slope and intercept. reg is a regression object with a coef method. If this returns a vector of length 1 then the value is taken to be the slope of a line through the origin, otherwise, the first 2 values are taken to be the intercept and slope.

Fixed- and Mixed-Effects Regression Models in R

The slope of the regression line is called coefficient and the point where the regression line crosses the y-axis is called the intercept. A word about standard errors (SE) is in order here because most commonly used statistics programs will provide SE values when reporting regression models.

On the other hand, if you’ve got a line which is “wobbly” and you don’t know why it’s wobbly, then a good starting point would probably be locally weighted regression, or loess in R. This does linear regression on a small region, as opposed to the whole dataset.
