treeDists()所属R语言包:clstutils
Provide objects for determining distances among nodes of a reference tree.
提供对象确定的参考树的节点之间的距离。
译者:生物统计家园网 机器人LoveR
描述----------Description----------
Provides objects (dists, paths) that can be used to calculate vectors of distances between an internal node and each leaf node. Also returns a square matrix of distances between leaf nodes.
提供的对象(dists目录路径),可以用来计算一个内部节点,每个叶子节点之间的距离向量。叶节点之间的距离也返回一个方阵。
用法----------Usage----------
treeDists(placefile, distfile)
参数----------Arguments----------
参数:placefile
path to pplacer output
pplacer输出路径
参数:distfile
path to output of guppy distmat
路径输出guppy distmat
Details
详情----------Details----------
A placement on an edge looks like this:
一个边缘的位置,看起来像这样:
值----------Value----------
A list with the following elements:
具有下列内容的列表:
参数:dists
rectangular matrix of distances with rows corresponding to all nodes in pplacer order, and columns corresponding to tips in the order of the corresponding phylo{ape} object.
在pplacer为了所有节点的相应行的距离,和相应的提示,在相应的phylo{ape}对象的顺序列的长方形矩阵。
参数:paths
rectangular matrix in the same configuration as dists with values of 1 or -1 if the path between nodes is serial or parallel, respectively (see Details)
在相同配置的长方形矩阵dists值1或-1,如果节点之间的路径是串行或并行,分别为(见详情)
参数:dmat
square matrix containing distances between pairs of tips.
方阵包含提示对之间的距离。
注意----------Note----------
The output of this function is required for classifyPlacements.
这个函数的输出需要classifyPlacements。
