How to deal with the "Error: Continuous value supplied to discrete scale" in R Groups)) + geom_boxplot() + scale_color_manual(values = c("red", "green", How to avoid the "Error: Continuous value supplied to discrete scale" in R - 2 R programming examples - Programming syntax in RStudio. Default colours are generated with munsell and mnsl(c("2.5PB 2/4", "2.5PB 7/10")) . Generally, for continuous colour scales you want to keep hue constant, but Use gray colors; Continuous colors scale_fill_manual() for box plot, bar plot, violin plot, etc; scale_color_manual() for lines and points. On the other hand, some aesthetics, like size, can vary continuously but others like In contrast with scale_color_manual() the user needs to explicitly11.2 Continuous colour scales. Colour gradients are often used to show the height of a 2d surface. The plots in this section use the surface of a 2d density Mapping continuous values to a color scale requires a continuously changing palette of colors. Table 12.2. lists the continuous color and fill scales. Table
