Description

检索所查询分类单元概念的所有子概念或父概念。

Usage

get_children(taxlist, ...)## S3 method for class 'taxlist'get_children(taxlist, ConceptID, ...)get_parents(taxlist, ...)## S3 method for class 'taxlist'get_parents(taxlist, ConceptID, ...)

Arguments

参数【taxlist】：一个 taxlist 对象。

参数【…】：方法之间传递的进一步参数。

参数【ConcertID】：用于选择父或子或分类表子集的概念id。

Details

该方法生成 taxlist 对象的子集，包括所查询分类单元概念的所有子或父级概念。

在这些方法中可以查询多个概念。

参数【ConceptID】可以是一个概念ID的向量，或是一个输入的 taxlist 对象的子集。

Value

一个 taxlist 对象，包含所请求的概念以及父子级。

Examples

准备一个科级子集：

Ebenaceae <- subset(x = Easplist, subset = TaxonName == "Ebenaceae")Ebenaceae
object size: 6.7 Kb validation of 'taxlist' object: TRUE number of taxon usage names: 1 number of taxon concepts: 1 trait entries: 0 number of trait variables: 1 taxon views: 3 hierarchical levels: form < variety < subspecies < species < complex < genus < family number of concepts in level form: 0number of concepts in level variety: 0number of concepts in level subspecies: 0number of concepts in level species: 0number of concepts in level complex: 0number of concepts in level genus: 0number of concepts in level family: 1

根据子集，去检索子概念：

Ebenaceae <- get_children(Easplist, Ebenaceae)Ebenaceae
object size: 8.5 Kb validation of 'taxlist' object: TRUE number of taxon usage names: 10 number of taxon concepts: 9 trait entries: 0 number of trait variables: 1 taxon views: 3 concepts with parents: 8 concepts with children: 3 hierarchical levels: form < variety < subspecies < species < complex < genus < family number of concepts in level form: 0number of concepts in level variety: 0number of concepts in level subspecies: 0number of concepts in level species: 6number of concepts in level complex: 0number of concepts in level genus: 2number of concepts in level family: 1

再准备一个种级子集：

Diostri <- subset(x = Easplist, subset = TaxonConceptID == 52403,slot = "relations")Diostri
object size: 6.7 Kb validation of 'taxlist' object: TRUE number of taxon usage names: 1 number of taxon concepts: 1 trait entries: 0 number of trait variables: 1 taxon views: 3 hierarchical levels: form < variety < subspecies < species < complex < genus < family number of concepts in level form: 0number of concepts in level variety: 0number of concepts in level subspecies: 0number of concepts in level species: 1number of concepts in level complex: 0number of concepts in level genus: 0number of concepts in level family: 0

随即查找它的父概念：

Diostri <- get_parents(Easplist, Diostri)Diostri
object size: 7.1 Kb validation of 'taxlist' object: TRUE number of taxon usage names: 3 number of taxon concepts: 3 trait entries: 0 number of trait variables: 1 taxon views: 3 concepts with parents: 2 concepts with children: 2 hierarchical levels: form < variety < subspecies < species < complex < genus < family number of concepts in level form: 0number of concepts in level variety: 0number of concepts in level subspecies: 0number of concepts in level species: 1number of concepts in level complex: 0number of concepts in level genus: 1number of concepts in level family: 1
