Withggplot2I want to bin continous values into three bins and assign a specific color to each of them. In the following code example I want all values < 10 to be black, values >=10 and <= 100 to be red, and all values > 100 to be white. ...
Now I want to be able to set the line color and style (need it in grey values), add the two straight lines to the legend and remove the title of the legend. This code works (I put fake data): library(ggplot2)load("vns.data")load("rw.data")load("gibbs.data") ...
The goal of this article is to describe how to change the color of a graph generated using R software and ggplot2 package. A color can be specified either by name (e.g.: “red”) or by hexadecimal code (e.g. : “#FF1234”). The different color systems available in R are describe...
