Step 3: Add R-Squared to the Plot (Optional).In this article, we will discuss how a scatter plot with linear regression can be drafted using R and its libraries.

Here is one solution # GET EQUATION AND R-SQUARED AS STRING # SOURCE: portalnews.top#!topic/ggplot2/1TgH-kG5XMA lm_eqn <- function(df){ m.I guess my problem is that I want to achieve too complex things for my level of programming skills, but how do I know what's the right level of complexity is.

Add regression line equation and R^2 to a ggplot. Regression model is fitted using the function lm. stat_regline_equation(mapping = NULL, data = NULL.Another option would be to create a custom function generating the equation using dplyr and broom libraries:.

In R, adding the regression line equation and the R-squared to your ggplot2 visualizations is harder then you'd expect it to be.Thank you for your assistance. 9. ### Vudogal

The geom_smooth() function makes it easy to add a simple linear regression line to a scatterplot of the corresponding variables. And in fact, there are more.It should be noted that the x and y in the formula refer to the x and y data in the layers of the plot, and not necessarily to those in scope at the time my.

Having the option to display model coefficients and R2 as plot annotation would be a great extension of geom_smooth() or stat_smooth() functions.All objects will be fortified to produce a data frame. 15. ### Mosho
