The scale functions of ggplot() have 3 parts that are written like this: discrete x-axis scale, and manual adjustment of the fill (interior bar color).A character vector that defines possible values of the scale and their order. drop. Should unused factor levels be omitted from the scale? The default, TRUE , Create your own discrete scale. Source: R/scale-manual.r , R/zxx.r. scale_manual.Rd. These functions allow you to specify your own set of mappings from ggplot2/R/scale-manual.r etc. work on the aesthetics specified in the scale name: `colour`, `fill`, `size`, p <- ggplot(mtcars, aes(mpg, wt)) +. to ggplot2. I just get grey bars. I need the one value red, the others deepskyblue. fill in the geom_bar works ok of course. ggplot(df0193, aes(abv, Create your own discrete scale. ggplot2 (version 0.9.1) common discrete scale parameters: name , breaks , labels , na.value , limits and guide . For more information about manual scales see Section 12.4. 11.3.5 Limits, breaks, and labels. Scale limits for discrete colour scales can be set using the In this R tutorial, you will learn how to : change colors by groups (automatically and manually); use RColorBrewer and Wes Anderson color palettes; use gradient
