library(ggplot2)

## generate a plot with the Exploristics theme
cars_plot <- ggplot(data = mtcars, aes(x = hp, y = mpg, colour = mpg)) +
geom_point(size=2) +
exploristics_theme()

## adding the colour scheme can be written as one line
exploristics_colour(cars_plot, colour_pal="Expl_RGB")



library(magrittr)

## or using a pipe
cars_plot %>%
exploristics_colour(colour_pal="Expl_RGB")
