Packagetaxlistversion 0.2.4


Description

分类层次结构可以设置为 taxlist 对象中的级别,按从低到高的顺序排列。

在 taxlist 对象中为特定分类概念添加分类级别。此外,概念限制的变化可能涉及其分类层次结构的变化。


Usage

levels(x)## S3 method for class 'taxlist'levels(x)levels(x) <- value## S3 replacement method for class 'taxlist'levels(x) <- value

Arguments

参数【x】:一个 taxlist 对象。

参数【value】:替换值的字符向量。


Details

分类级别将作为 taxlist 对象中的因子进行处理。这些级别对于创建相关组的子集很有用(例如,通过函数 get_children() 或 get_parents())。

与父子关系相结合的级别将进一步用于检查分类列表的一致性。

还实现了表单 levels(x) <- value 的替换方法。


Value

具有添加或修改的分类级别的字符向量或 taxlist 对象。
