updateFrame(SamplingStrata)
updateFrame()所属R语言包：SamplingStrata
Modification of the initial frame on the basis of optimised strata aggregation
的最初的帧的基础上优化地层聚合改性
译者：生物统计家园网 机器人LoveR
描述----------Description----------
Once optimal stratification has been obtained, and new labels have been attributed to initial atomic strata ("newstrata"), it is important to report the new classification of units in the sampling frame by attributing new strata labels to each unit. By executing this function, a new frame will be obtained with the same structure of the old, but the addition of a new stratum label. It is important that the old frame contains a variable named 'domainvalue' that reports the values of the domain that has been used with the 'optimizeStrata' function. If no domains have been defined, this variable will contains all 1's, but it must exist
一旦最佳分层得到，和新的标签已被归因于初始原子地层（“newstrata”），它是重要的报告通过归因新地层标签给每个单元的采样帧中的新的分类的单位。通过执行该功能，将获得一个新的帧具有相同的结构的旧，但另外一个新的层标签。重要的是，旧的框架中包含一个名为“domainvalue”，该报告已被用于的“optimizeStrata功能域的值的变量。如果没有域已经确定，这个变量将包含所有的，但是它必须存在
用法----------Usage----------
updateFrame(frame, newstrata)
参数----------Arguments----------
参数：frame
This is the (mandatory) dataframe containing the sampling frame.
这是（强制性的）数据框的抽样框。
参数：newstrata
This is the (mandatory) dataframe containing the information related to the optimisation applied to initial stratification (new labels applied to atomic strata). It is produced by executing the "updateStrata" function.
这是含有施加到初始的分层（新的标签施加原子地层）的优化的相关信息（强制）数据框。它是由执行“updateStrata”功能。
值----------Value----------
A dataframe containing the frame
一个数据框包含帧
