Removing legend
We can remove the legend by providing “none” in legend.position as an argument of theme() function. The legend.position argument refers to the position of the legends.
Syntax :
theme( legend.position = “none”, … , complete = FALSE, validate = TRUE)
Example: R program to remove legends
R
# Installing and loading the package library (ggplot2) # Read the dataset data ( "USArrests" ) # Plot the data plt <- ggplot (USArrests, aes (Murder, Assault, colour = UrbanPop))+ geom_point () # Removing legend plt + theme (legend.position = "none" ) |

Working with Legends in R using ggplot2
A legend in a plot helps us to understand which groups belong to each bar, line, or box based on its type, color, etc. We can add a legend box in R using the legend() function. These work as guides. The keys can be determined by scale breaks. In this article, we will be working with legends and associated customization using ggplot2 in R programming language.
Syntax :
legend(x, y = NULL, legend, fill = NULL, col = par(“col”), border = “black”, lty, lwd, pch)
