This week, we will see how to connect two points with a straight line in base R and ggplot2. For this, we need to compute the slope and the intercept.…

We will see how to perform exponential regressions and how to plot these curved regression lines in base R and ggplot2, using the lines and geom_line functions, respectively. Please read…

In this tutorial, we will see how to perform a local polynomial regression using the loess function and how to plot curved regression lines in base R and ggplot2. We…

We will see how to perform a linear regression using the lm function and to plot these straigth regression lines in base R and ggplot2, using the lines and geom_abline…

To add curved lines to plots in base R, we need the lines function. And to do it in ggplot2, we need the geom_line function. In the example below, we…

In this article, we will see how to add straight (vertical, horizontal and diagonal) lines to plots in base R and in ggplot2. As an example, we will use the…

In this tutorial, we will see how to make bar plots with error bars in R using the ggplot2 package. For that, we will go through two examples using the…

In this tutorial, we will see how to create and rotate 4 types of heatmaps in R with the ggplot2 package. In heatmaps, the diagonal line is always 1, which…

In this article, we will review the 26 types of point shapes that we can draw in base R and the ggplot2 package. The shape codes range from 0 to…

In this blog post, I will cover 12 of the most common types of plots in R using ggplot2. To begin, we will load the ggplot2 package and the iris…
