Can the R ggplot package be used in the Open Source Code node for visualization purposes?
Yes, you can use the Open Source Code node in Model Studio to visualize plots using ggplot2 package in R software. Other Python or R visualization packages can also be used. The plots need to be saved as image files with rpt_ prefix and .png, .jpeg or .gif file extension. They will be displayed in the Results after the successful execution of the Open Source Code node.
Multiple visualizations using ggplot2 and rpart.plot packages are shown in this GitHub example.
Note that the above example requires pre-installation of rpart, rpart.plot and ggplot2 packages in R software on the Compute Server.
