Subject: [R] how to show a dataset in 3d?
my dataset looks like this in the beginning:
Subject Time1 Time2 Time3
1 1 0.385 0.103 -0.488
2 2 -1.939 0.569 1.370
3 3 -1.196 -0.051 1.247
4 4 0.174 -1.163 0.989
5 5 1.246 0.558 -1.804
6 6 -1.108 -0.057 1.165
7 7 -0.609 -0.344 0.953
so each subject has three observations. now I need to show the dataset in 3d
with scatterplot3d and plot3d together, that's what I don't know how it works.
I tried:
scatterplot3d(data, type="p", highlight.3d=T, pch=16)
the graph looks like 3D but is not reall 3D, I mean I can't e.g. rotate it.
but how can combine both functions?
