21 Sep 2015 We pay great attention to regression results, such as slope coefficients, p-values, or R2 that tell us how well a model represents given data. That's An important part of assessing regression models is visualizing residuals. If you use plot(model1) four residual plots will be produced that provide some insights. Plotting the Regression Line. The R command abline adds a line to a plot. Putting this all together. Overview of R graphics. 2. Standard graphics Session 2: Standard graphics in R. ▫ R object-oriented Anova/regression: lm() → an “lm” object. • Generalized R - Linear Regression - Regression analysis is a very widely used statistical Mathematically a linear relationship represents a straight line when plotted as a

R makes it very easy to create a scatterplot and regression line using an lm object created by lm function. We will illustrate this using the hsb2 data file. hsb2< -read.

One of the simplest R commands that doesn't have a direct equivalent in Python is plot() for linear regression models (wraps plot.lm() when fed linear models).
