custom legend ggplot code example

Example 1: ggplot2 remove legend

### Three options (where p is the plot object)

# Remove the legend title: 
p + theme(legend. title = element_blank())

# Hide the entire legend to create a ggplot with no legend. 
p + theme(legend. position = "none") 

# Hide legend for a specific geometry, say geom_text(). 
p + geom_text(show.legend = FALSE)

Example 2: how to change labels on legend ggplot

scale_color_manual(values = c("#D16103", "#4E84C4"),
                     labels = c("Justin", "Myself"))

Example 3: ggplot put legend in plot

p + theme(legend.position = c(0.8, 0.2))

Example 4: turn legend off ggplot2

bp + theme(legend.position="none")
