Manual scale ggplot

ggplot fill color based on valuescale_fill_discrete
scale_fill_discrete palette
scale_fill_continuous(limits)
error: continuous value supplied to discrete scale
scale fill gradient
scale fill manual colors
scale color manual not working

ggplot2/R/scale-manual.r etc. work on the aesthetics specified in the scale name: `colour`, `fill`, `size`, p <- ggplot(mtcars, aes(mpg, wt)) +. Simple plots. library(ggplot2) # Box plot ggplot(ToothGrowth, aes(x=dose, y=len)) +geom_boxplot() # scatter plot ggplot2 (version 2.2.1). scale_manual: Create your own discrete scale p <- ggplot(mtcars, aes(mpg, wt)) + geom_point(aes(colour = factor(cyl))) p + The second group of continuous colour scales built in to ggplot2 are derived from the you can use scale_fill_manual() to set the colours manually. Source: R/scale-manual.r , R/zxx.r scale_colour_manual(values = cols) # You can set color and fill aesthetics at the same time ggplot( mtcars, aes(mpg, Source: R/scale-manual.r , R/zxx.r. scale_manual.Rd. These functions allow you to specify your own set of mappings from levels in the data to aesthetic It would be tedious to manually add a scale every time you used a new ggplot(mpg, aes(displ, hwy)) + geom_point() + scale_x_continuous("Label 1") +
