Rgl.lines(c(0, 0), c(0, 0), c(min(z),max(z)), color = "green")Īs you can see, the axes are drawn but the problem is that they don’t cross at the point c(0, 0, 0) Rgl.spheres(x, y, z, r = 0.2, color = "yellow") To draw an axis, you should specify the range (minimum and the maximum) of the axis to the function rgl.lines(): # Make a scatter plot In this case, the argument y and z can be omitted. Note also that, the argument x can be a matrix or a data frame containing, at least, 3 columns corresponding to the x, y and z coordinates, respectively. The values x2, y2 and 圓 corresponds to the 3D coordinates of the line ending point.The values x1, y1 and 圓 are the 3D coordinates of the line starting point.R3D is a collection of generic 3D objects and functions which are described at the end of this article.įor the function rgl.lines(), the arguments x, y, and z are numeric vectors of length 2 (i.e, : x = c(x1,x2), y = c(y1, y2), z = c(z1, z2) ). The rgl package includes also a generic 3D interface named R3D. It allows to interactively rotate, zoom the graphics and select regions. RGL is a 3D graphics package that produces a real-time interactive 3D plot. You’ll learn also how to create a movie of your 3D scene in R. This R tutorial describes, step by step, how to build a 3D graphic using R software and the rgl package. Export the plot into an interactive HTML file.Set the aspect ratios of the x, y and z axes.rgl_add_axes(): A custom function to add x, y and z axes.rgl_init(): A custom function to initialize RGL device.
