类对象----------Objects from the Class----------
Objects can be created by calls of the form new("TwoStageControl", ...) or via the constructor TwoStageControl.
可以创建对象通过调用的形式new("TwoStageControl", ...)或通过构造TwoStageControl的。
插槽----------Slots----------
design: Object of class "BasicVector" specifying variables (columns) to be used for stratified sampling in the first
design：对象的类"BasicVector"指定变量（列），以用于在第一分层抽样
grouping: Object of class "BasicVector" specifying grouping variables (columns) to be used for sampling primary sampling
“”grouping：对象类"BasicVector"指定分组变量（列）用于初级抽样取样
fun: Object of class "list"; a list of length two containing the functions to be used for sampling in the first and second stage, respectively (defaults to srs for both stages). The functions should return a vector containing the indices of the sampled
fun：类对象的"list";包含要用于抽样检验在第一和第二阶段，分别（默认为srs的两个阶段）的功能的列表的长度2。函数应该返回一个向量，包含的采样的指数，其中
size: Object of class "list"; a list of length two, where each component contains an optional non-negative integer giving the number of items to sample in the first and second stage, respectively. In case of stratified sampling in the first stage, a vector of non-negative integers, each giving the number of PSUs to sample from the corresponding stratum, may be supplied. For the second stage, a vector of non-negative integers giving the number of items to sample from each
size：对象类"list";的列表的长度为2的方法，其中每个组件包含一个可选的非负整数，分别在第一和第二阶段的样品，给予的项目数。以分层抽样的情况下，在第一阶段中，一个向量的非负整数，每个样品从对应的阶层的PSU的数量，可提供。给予的项目数的向量的非负整数，在第二阶段，从每个取样
prob: Object of class "list"; a list of length two, where each component gives optional probability weights for the first and second stage, respectively. Each component may thereby be a numerical vector, or a character string or integer vector specifying a variable
prob：类对象的"list";长度为两个，其中每个组件给出了可选的概率加权分别为第一和第二阶段中，一个列表。由此，每个组件可以是一个数值矢量，或者是一个字符串或整数矢量指定一个变量
dots: Object of class "list"; a list of length two, where each component is again a list containing additional arguments to
dots：类的对象"list";长度为二的列表，其中每个组件又是一个列表，其中包含额外的参数
k: Object of class "numeric"; a single positive
k类的对象"numeric";一个单一的正

详细信息----------Details----------
There are some restrictions on the argument names of the functions for sampling in fun. If the sampling method needs population data as input, the corresponding argument should be called x and should expect a data.frame. If it only needs the population size as input, the argument should be called N. Note that the function is not expected to have both x and N as arguments, and that the latter is typically much faster. Furthermore, if the function has arguments for sample size and probability weights, they should be called size and prob, respectively. Note that a function with prob as its only argument is perfectly valid (for probability proportional to size sampling). Further arguments may be supplied as a list via the slot dots.
在fun采样参数的函数名上有一些限制。如果采样方法需要人口数据作为输入，相应的参数应该被称为x和预期data.frame。如果只需要输入的人口规模，参数应该被称为N。请注意，该功能预计不会有两个x和N作为参数，而后者通常是更快的。此外，如果该函数有参数样本大小和概率权重，他们应该被称为size和prob“。需要注意的是同一个函数prob作为其唯一的参数是完全合法的概率成比例规模抽样。可以提供进一步的论据，通过槽dots为一个列表。
