描述----------Description----------
Return the first parts of an object.
返回对象的第一部分。
用法----------Usage----------
## S4 method for signature 'SampleSetup'
head(x, k = 6, n = 6, ...)
## S4 method for signature 'SimControl'
head(x)
## S4 method for signature 'SimResults'
head(x, ...)
## S4 method for signature 'Strata'
head(x, ...)
## S4 method for signature 'VirtualContControl'
head(x)
## S4 method for signature 'VirtualDataControl'
head(x)
## S4 method for signature 'VirtualNAControl'
head(x)
## S4 method for signature 'VirtualSampleControl'
head(x)
参数----------Arguments----------
参数:x
an object.
一个对象。
参数:k
for objects of class "SampleSetup", the number of set up samples to be kept in the resulting object.
类的对象"SampleSetup",成立的样品被保存在生成的目标。
参数:n
for objects of class "SampleSetup", the number of indices to be kept in each of the set up samples in the resulting object.
类的对象"SampleSetup",指数保持在每个样品中生成的对象的设置。
参数:...
additional arguments to be passed down to methods.
额外的参数传递的方法。
值----------Value----------
An object of the same class as x, but in general smaller. See the “Methods” section below for details.
x,但在一般较小的同一类的一个目的。 “方法”一节的详细信息。
方法----------Methods----------
signature(x = "SampleSetup") returns the first parts of set up samples. The first n indices of each of the first k set up
signature(x = "SampleSetup")返回的第一部分成立的样品。第一n指数,其中每个所述第一k成立
signature(x = "SimControl") currently returns the
signature(x = "SimControl")返回
signature(x = "SimResults") returns the first parts of simulation results. The method of head for the
signature(x = "SimResults")返回的模拟结果的第一部分。 head的方法
signature(x = "Strata") returns the first parts of strata information. The method of head for the vector in slot values is thereby called and the slots split and
signature(x = "Strata")返回的第一部分地层信息。的方法head为向量在插槽values从而称为和插槽split的
signature(x = "VirtualContControl") currently returns the
signature(x = "VirtualContControl")返回
signature(x = "VirtualDataControl") currently returns the
signature(x = "VirtualDataControl")返回
signature(x = "VirtualNAControl") currently returns the
signature(x = "VirtualNAControl")返回
signature(x = "VirtualSampleControl") currently returns the
signature(x = "VirtualSampleControl")返回

实例----------Examples----------
## load data[#加载数据]
data(eusilcP)
## class "SampleSetup"[#类“SampleSetup”]
# set up samples using group sampling[采用整群抽样的样本]
set <- setup(eusilcP, grouping = "hid", size = 1000, k = 50)
summary(set)
# get the first 10 indices of each of the first 5 samples[得到的第一个10指数,其中的第一个5个样本,每个]
head(set, k = 5, n = 10)
## class "Strata"[#类“阶层”]
# set up samples using group sampling[采用整群抽样的样本]
strata <- stratify(eusilcP, "region")
summary(strata)
# get strata information for the first 10 observations[获得的第10个观察地层信息]
head(strata, 10)
