In the below example, we create histogram of the variable Now, let’s have a look at our current clean titanic dataset. This post will focus on making a Histogram With ggplot2. First, let’s have a look at how the Age is distributed. To display the curve on the histogram using ggplot2, we can make use of geom_density function in which the counts will be multiplied with the binwidth of the histogram so that the density line will be appropriately created. Now, let’s have a look at our current clean titanic dataset. This concept is explained in depth in data-to-viz. The package is available through both CRAN (install.packages("ggExtra")) and GitHub (devtools::install_github("daattali/ggExtra")).
