小波重建WD类对象（反离散小波变换）。
译者：生物统计家园网 机器人LoveR
描述----------Description----------
This function performs the reconstruction stage of Mallat's pyramid algorithm (Mallat 1989), i.e. the discrete inverse wavelet transform. The actual transform is performed by some C code, this is dynamically linked into S (if your machine can do this).
此功能进行Mallat的金字塔算法（MALLAT 1989年）重建阶段，即离散小波逆变换。实际的变换是由一些C代码，这是动态地链接到S（如果你的机器可以做到这一点）。
用法----------Usage----------
## S3 method for class 'wd':
wr(wd, start.level = 0, verbose = FALSE, bc = wd$bc,
return.object = FALSE, filter.number = wd$filter$filter.number,
family = wd$filter$family, ...)
参数----------Arguments----------
参数：wd
A wavelet decomposition object as returned by wd, and described in the help for that function and the help for wd.object.
一种基于小波分解的对象返回的wd，并描述了该功能的帮助wd.object的帮助。
参数：start.level
The level you wish to start reconstruction at. The is usually the first (level 0). This argument is ignored for a wd object computed using the “wavelets on the interval” transform (i.e. using the bc="interval" option of wd.
你想开始重建工作的水平。通常是第一个（0级）。此参数将被忽略为计算的WD对象，使用“区间上的小波变换（即使用bc="interval"选项的wd。
参数：verbose
Controls the printing of "informative" messages whilst the computations progress. Such messages are generally annoying so it is turned off by default.
控制打印的“信息”的消息，而计算的进展。这样的消息一般都是讨厌的，所以它在默认情况下是关闭的。
参数：bc
The boundary conditions used. Usually these are determined by those used to create the supplied wd object, but you sometimes change them with possibly silly results.
所使用的边界条件。通常情况下，这些都取决于用于创建所提供的WD对象，但你有时会改变他们的结果可能是愚蠢的。
参数：filter.number
The filter number of the wavelet used to do the reconstruction. Again, as for bc, you should probably leave this argument alone. Ignored if the bvc component of the wd object is "interval".
该过滤器使用的小波做的重建。同样地，bc的，你应该离开这个说法孤独。 BVC wd对象的组成部分，是“interval”忽略。
参数：family
The type of wavelet used to do the reconstruction. You can change this argument from the default but it is probably NOT wise. Ignored if the bvc component of the wd object is "interval".
小波的类型用来做什么的重建。您可以改变这个参数的默认值，但它可能不是明智的做法。 BVC wd对象的组成部分，是“interval”忽略。
参数：return.object
If this is F then the top level of the reconstruction is returned (this is the reconstructed function at the highest resolution). Otherwise if it is T the whole wd reconstructed object is returned. Ignored if the bvc component of the wd object is "interval".
如果这是F，那么重建的顶层被返回（这是在最高分辨率的重构函数）。否则，如果它是T WD整个重建对象返回。如果忽略bvc组成部分，wd对象是“interval”。
参数：...
any other arguments
任何其他参数
Details
详细信息----------Details----------
The code implements Mallat's inverse pyramid algorithm. In the reconstruction the quadrature mirror filters G and H are supplied with c0 and d0, d1, ... d(m- 1) (the wavelet coefficients) and rebuild c1,..., cm.
该代码实现Mallat的倒金字塔算法。在重建的正交镜像滤波器G和H的供给与c0和D0，D1，... D（m-1的）（小波系数）和重建c1的，...，厘米。
If the bc component of the wd object is "interval" then the wr.int function which implements the inverse “wavelet on the interval” transform due to Cohen, Daubechies and Vial, 1993 is used instead.
如果bc的组成部分wd对象是“interval”wr.int功能，实现了反“小波的间隔”改造科恩，Daubechies小波和样品瓶，1993来代替。
值----------Value----------
Either a vector containing the top level reconstruction or an object of class wd containing the results of the reconstruction, details to be found in help for wd.object.
无论是一个向量，包含的顶层重建或对象级WD的重建，帮助wd.object被发现的细节。
