Fitted line plot
WebFitted line plots are a special type of scatterplot that displays the data points along with a fitted line for a simple regression model. This graph allows you to evaluate how well the model fits the data. Use scatterplots to assess the following features of your dataset: Examine the relationship between two variables.

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 WebJul 8, 2024 · You were spot on on the intent, I have multiple data sets and multiple fit lines, hence the need to differentiate them by style and color. Introducing the argument fit_semi(2) solves the issue. Formatting of the line does affect the data points but I solved that by moving the fit line formatting upstream of the scatter plotting command.
