Line plots in R and R-Instat: Following the R script in R-Instat?
Our main aim is to show how to use the graphics dialogs in R-Instat. We join many enthusiasts for the grammar of graphics system in R, so the ggplot2 package. We have tried to make it easy to use, while still giving access to its amazing flexibility.
In this presentation we run and adapt the script itself.

Additional - Produce a Script and Change It.
Using the R-Instat dialogs we were able to recreate most of the graphs, but we could not add closed arrows ends to both ends of the arrow graph. Some may feel that using open arrow ends is good enough, but for those who wish to challenge themselves this is a great time to use R-Instat's To Script system.
To script, is designed for those who are open to using but do not want to write them from scratch. You can use the R-Instat dialog to generate the full command and then make small changes to suit your needs.
