Is there a way to customize the labels in a legend when utilizing ggboxplot? I have a barplot with a legend in which the labels are taken from the data frame columns. I would like to change these labels without having to change the label of the column. Something akin toscale_fill_discrete(labels=c(......) in ggplot.

I tweaked @Nicolás Velásquez answer a bit. You can also use

scale_fill_discrete(labels = c("First", "Second"))

This also works for gghistogram

Certainly. Ggplot2's scale_x_discrete() will do the trick. 

ggBoxplot(as.data.frame(DFW2), y = 'shares', x = 'Polaridad') +
          scale_x_discrete(labels = c("First", "Second"))

ggboxplot() is but a wrapper around ggplot2's ggplot() and geom_box() functions, so all instructions for layers after ggplot() will work.
