2D and 3D graphing
rgl can do that, but I have my doubts whether it is useful: x <- runif(500) y <- runif(500) z <- (x - 0.5)^2 + (y - 0.5)^2 library(rgl) plot3d(x, y, z, col = "red") dxyz <- deldir::deldir(x, y, z = z, suppressMsge = TRUE) plot3d(dxyz, add = TRUE, front = "lines", back = "lines", specular = "black") Duncan Murdoch

Thank you Jeff. I have been using a textbook which has some of the chart types i was hoping to produce; that's 3D charts where points are connected by lines in 3D, like a grid. The book also has 3D fitted surfaces. The authors used exclusively R in this book. That's what i asked.
Thanks again and hope you and yours are safe

I don't know of any 3d scatterplot plotting software that does that. You have to communicate the connections between points to the plotting function, and there is no easy way to do that with arbitrary scattered points. That is why the surface3d function interface is separate from the points3d function interface ... it uses a matrix to communicate adjacency for four points at a time.

Thank you Ista and LMH. I want to plot 3D scatter with options to connect the surface with lines;that's just like points connected with a? line in 2D and i may want to fit a surface to the data for soem of teh plots. LMH pointed out to what concerned me and the reason for the question which was i don't want to spend time in a package and then find out that t doesn't do what i want to. Thanks again and best of luckEK On Monday, March 23, 2020, 6:02:33 PM EDT, LMH <lmh_users-groups at molconn.com> wrote: Hello, I use rgl for 3D plots. Mostly I use this for a 3D scatter plot where I can zoom and pan for closer analyses of the data. I also can manually connect any points with lines. It took me a bit to get the options right so the plot appears the way I want it to. In my opinion, there are a few unresolved issues with the units and labels on the axis, but most of the data I looked at was in principle components so x, y, and z were in the same units. I can post a sample of the terminal input that I used if that would help. LMH Ek Esawi wrote:
Hi All-- I have been looking into 2D and 3D graphing packages. Based on what i read, it seems that ggplot2 is the best and I like it too, but
ggplot2
doesn't have 3D plotting capabilities. I read that other packages (plot_ly, rgl, rayshader) can be used with ggplot2 to create 3D charts, but not sure if that?s the way to go. The question is: what is/are the best 2D and 3D graphing packages? I read that lattice, and a few others, has ?limited? 3D charting capabilities. Thanks in advance--EK
