图片中是计算的具体公式，自己编程太麻烦了，Rao's quadratic entropy  肯定有一些包是能直接算的，希望大神们能帮助我

FD: Measuring functional diversity (FD) from multiple traits, and other tools for functional ecology
FD is a package to compute different multidimensional FD indices. It implements a distance-based framework to measure FD that allows any number and type of functional traits, and can also consider species relative abundances. It also contains other useful tools for functional ecology.

这个网站我也看到了，但函数的具体使用方法我还是不会，能请教一下你吗

求各位大神能指点一二，计算功能性状alpha，beta多样性，用什么包，包里的什么函数，数据的格式是什么样的等。拜谢！
