how to rename the legend of a 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: labs fill ggplot2
df <- data.frame(x=1:10,group=c(rep("a",5),rep("b",5)))
legend_title <- "OMG My Title"
ggplot(df, aes(x=x, fill=group)) + geom_density(alpha=.3) +
scale_fill_manual(legend_title,values=c("orange","red"))
