In this tutorial, I’ll demonstrate how to draw a 3D Plot of a Principal Component Analysis (PCA) in the R programming language. This is the table of content: 1) Prepare Data and Load Add-On Library

二、绘制3d pca图. 3d pca样本图其实就是3d散点图，如果要绘制3d pca双序图，可以以箭头等其他形式展示变量。绘图原理都是差不多的，本质上都需要提供坐标信息，向图中添加各种需要的元素并设置图中的各种参数美化图形。

Visualize Principle Component Analysis (PCA) of your high-dimensional data in R with Plotly. This page first shows how to visualize higher dimension data using various Plotly figures combined with dimensionality reduction (aka projection).

Feb 3, 2013 · We'll use the excellent rgl package, which you can install with install.packages("rgl") if you haven't already. We'll plot the scores along the first three principal components for each iris, and color by species. That plot will be interactive: click and drag to rotate, right click and drag or use the mouse wheel to zoom.
