library("ggplot2") # Load ggplot2
ggp ＜- ggplot(data, aes(x, y, color = y)) + # ggplot2 scatterplot with default legend
geom_point()
ggp # Draw ggplot2 scatterplot
fun_color_range ＜- colorRampPalette(c("yellow", "red")) # Create color generating function
my_colors ＜- fun_color_range(20) # Generate color range
my_colors # Print color range
ggp + # Change colors in ggplot2 scatterplot
scale_colour_gradientn(colors = my_colors)
