Keep your messages in the list, you increase your chance to get some answer.
I changed your data to groupedData object (see below), but I did not find any
problem in it.

Seems to me, that something has
Hi,
Following Paul's instruction, I have installed the Cairo. I tried to run
the program, and there is no error message at all. I did see the Chinese
title in the plot if I ask my RStudio to show the plot (if I type "p1"),

Hi R-users,
I think that I have figured out what I should do. But I would welcome any
comments clarifying any of the questions that I have raised. (I am showing
my revised code below). The questions which are still unresolved for me are
the following :
1. With the points3d or the plot3D function,
(Re-)read the discussion of indexing (both `[` and `[[`) and be sure to get
clear on the difference between matrices and data frames in the Introduction to
R document that comes with R. There are many ways to create numeric vectors,
character vectors, and logical vectors that can then be used as
Hi R users and experts,
I am interested in learning more about the use of 3D plots. Specifically, I
want to add points and lines to a surface plot. And get the axes and labels
plotted also. Here is what I have tried with an example data set :
library(rgl)
vol2 <- 2*volcano # Exaggerate the relief
You really need to spend some time learning the basics of R. There are
thousands of R packages, so you also need to spend time reading the
documentation for the package so that you can show us what the data format
should be like. Here are some simple ways to transform the data. You should

Thanks a lot, so simple so efficient!
I will study more the grep command I did not know.
Thanks!
