WebMay 9, 2013 · For linear relationships we can perform a simple linear regression. For other relationships we can try fitting a curve. From Wikipedia: Curve fitting is the process of constructing a curve, or mathematical function, that has the best fit to a series of data points, possibly subject to constraints. WebFeb 22, 2024 · The abline () function in R can be used to add one or more straight lines to a plot in R. This function uses the following syntax: abline (a=NULL, b=NULL, h=NULL, v=NULL, …) where: a, b: single values that specify the intercept and slope of the line h: the y-value for the horizontal line v: the x-value for the vertical line
