Creating Visual Emphasis: Adding Dotted Boxes to Graphs in R Studio
I’ll explain how to insert a box in a graph to highlight it. I’ll generate some data. “This data pertains to the yield and standard error for five different genotypes. I’ll create a bar chart to visualize it. In this graph, genotypes D and E exhibit greater yields compared to the other genotypes. My current objective is to emphasize genotypes D and E by adding a dotted box. To achieve this, we can utilize the geom_rect(). For geom_rect(), I set…
