描述----------Description----------

Generic function for drawing a sample.
通用函数抽取一个样本。


用法----------Usage----------


draw(x, setup, ...)

## S4 method for signature 'data.frame,SampleSetup'
draw(x, setup, i = 1)

## S4 method for signature 'data.frame,VirtualSampleControl'
draw(x, setup)



参数----------Arguments----------

参数:x
the data to sample from.
的数据采样。


参数:setup
an object of class "SampleSetup" containing previously  set up samples, a control object inheriting from the virtual class  "VirtualSampleControl" or a character string specifying such a  control class (the default being "SampleControl").
类的一个对象"SampleSetup"包含以前成立的样品,控制对象从虚拟类继承"VirtualSampleControl"或一个字符串指定这样的控制类(默认是"SampleControl")。


参数:i
an integer specifying which one of the previously set up samples  should be drawn.
一个整数,指定哪一个以前成立的样品应当制定。


参数:...
if setup is a character string or missing, the slots of  the control object may be supplied as additional arguments.  See  "SampleControl" for details on the slots.
如果setup是一个字符串或丢失,控制对象的插槽,可以提供额外的参数。见"SampleControl"的插槽。


值----------Value----------

A data.frame containing the sampled observations.  In addition, the  column ".weight", which consists of the sample weights, is added to  the data.frame.
Adata.frame包含采样的意见。此外,列".weight",它包括的样本权重,添加到data.frame。


方法----------Methods----------




x = "data.frame", setup = "character" draw a sample using a  control class specified by the character string setup.  The slots of
x = "data.frame", setup = "character"绘制指定的字符串setup控制类的一个示例使用。的插槽




x = "data.frame", setup = "missing" draw a sample using a  control object of class "SampleControl".  Its slots may be supplied
x = "data.frame", setup = "missing"抽取样本使用的控制对象类"SampleControl"。它的时隙可以提供




x = "data.frame", setup = "SampleSetup" draw a previously set
x = "data.frame", setup = "SampleSetup"先前设置的绘制




x = "data.frame", setup = "VirtualSampleControl" draw a sample  using a control object inheriting from the virtual class
x = "data.frame", setup = "VirtualSampleControl"画一个示例使用一个控制对象从虚拟类继承

实例----------Examples----------


## load data[#加载数据]
data(eusilcP)

## simple random sampling[#简单随机抽样]
draw(eusilcP[, c("id", "eqIncome")], size = 20)

## group sampling[#整群抽样]
draw(eusilcP[, c("hid", "id", "eqIncome")],
    grouping = "hid", size = 10)

## stratified simple random sampling[#分层简单随机抽样]
draw(eusilcP[, c("id", "region", "eqIncome")],
    design = "region", size = c(2, 5, 5, 3, 4, 5, 3, 5, 2))

## stratified group sampling[#分层整群抽样]
draw(eusilcP[, c("hid", "id", "region", "eqIncome")],
    design = "region", grouping = "hid",
    size = c(2, 5, 5, 3, 4, 5, 3, 5, 2))
