JTree_Basis()所属R语言包：treelet
Constructs the orthonormal basis for the Treelet algorithm
构造标准正交基的Treelet算法
译者：生物统计家园网 机器人LoveR
描述----------Description----------
Returns information on the construction of the treelet orthonormal basis at each level of the tree up to the maximum tree height specified.
返回信息树的最大树高在每个级别上建设的treelet的标准正交基。
用法----------Usage----------
JTree_Basis(Zpos, T, PCidx, maxlev, all_nodes, whichsave)
参数----------Arguments----------
参数：Zpos
A matrix of dimension maxlev x 2. Each row records which two nodes/clusters of the tree were combined at each step in its construction.
的矩阵尺寸maxlev×2。的每一行的记录，其中两个节点/合并树簇在其结构中的每个步骤。
参数：T
This is a list with maxlev elements, where each element is a 2x2 Jacobi rotation matrix for each step of the treelet algorithm.
这是一个maxlev元素，其中每个元素是一个2×2的Jacobi旋转矩阵每个步骤的treelet算法的列表。
参数：PCidx
A matrix of dimension maxlev x 2, where each row is a permutation of (1,2) indicating which of the two nodes/clusters merged at that step is the sum variable (value of 1) and which is the difference (value of 2).
A矩阵的维度maxlev×2，其中的每一行是一个置换(1,2)表示合并在该步骤中的两个节点/聚类的总和变量（值1）和它的区别是（值为2）。
参数：maxlev
The maximum height of the tree. This must be an integer between 1 and nrow(X)-1.
树的最大高度。这必须是一个整数1和nrow(X)-1之间。
参数：all_nodes
A matrix of dimension maxlev x nrow(X) giving node/cluster labels at each step of the treelet algorithm. A label of zero indicates a node/cluster that was merged with another node/cluster and was the difference variable.
维的矩阵maxlevXnrow(X)给节点/聚类标签在每一步的treelet算法。零标签表示节点/聚类与另一个节点/聚类和合并的差异变量。
参数：whichsave
A vector containing the levels of the tree, specified as integers between 1 and maxlev, for which you want to save the basis functions and the covariance matrix.
一个向量，包含水平的树，指定为整数1和maxlev，你要保存的基础功能和协方差矩阵。
Details
详细信息----------Details----------
Note that with the exception of maxlev and whichsave, the arguments provided to this function are outputs from the Build_JTree function. This function is therefore not intended to be used as a stand-alone function, but in conjunction with Build_JTree. The wrapper function Run_JTree performs this connection.
请注意，除maxlev和whichsave，提供这个函数的参数是从Build_JTree功能的输出。此功能，因此不打算被用来作为一个独立的功能，但结合使用Build_JTree。包装功能Run_JTree进行连接。
值----------Value----------
参数：basis
This is a list with maxlev elements. Only those elements that are specified in the whichsave argument will be non-null entries in the list. For the non-null entries, this is the orthonormal treelet basis calculated at that level of the tree.
这是maxlev元素的列表。只有那些元素中指定的whichsave参数非空列表中的条目。对于非空条目，这是的标准正交treelet基础的树在这一水平计算。
