Utility functions for stratifying data
利用分层数据的功能
译者:生物统计家园网 机器人LoveR
描述----------Description----------
Generic utility functions for stratifying data. These are useful if not all the information of class "Strata" is necessary.
通用的实用功能分层数据。这些都是有用的,如果不所有信息类"Strata"的是必要的。
用法----------Usage----------
getStrataLegend(x, design)
getStrataSplit(x, design, USE.NAMES = TRUE)
getStrataTable(x, design)
getStratumSizes(x, design, USE.NAMES = TRUE)
getStratumValues(x, design, split)
参数----------Arguments----------
参数:x
the data.frame to be stratified. For getStratumSizes, it is also possible to supply a list in which each list element contains the indices of the observations belonging to the corresponding stratum (as returned by getStrataSplit).
data.frame进行分层。对于getStratumSizes,它也可以提供一个列表,其中每个列表元素包含属于相应的地层(如经由getStrataSplit)的观测的指数。
参数:design
a character, logical or numeric vector specifying the variables (columns) to be used for stratification.
一个字符,逻辑或数值向量指定要用于分层的变量(列)。
参数:USE.NAMES
a logical indicating whether information about the strata should be used as names for the result.
一个逻辑指示关于地层的信息是否应该被用作names为结果。
参数:split
an optional list in which each list element contains the indices of the observations belonging to the corresponding stratum (as returned by getStrataSplit).
这是一个可选列表,其中每个列表元素包含索引到相应的层(返回getStrataSplit)的意见。
值----------Value----------
For getStrataLegend, a data.frame describing the strata.
对于getStrataLegend,data.frame描述的地层。
For getStrataSplit, a list in which each element contains the indices of the observations belonging to the corresponding stratum.
对于getStrataSplit,一个列表,其中每个元素包含指数的属于对应的阶层的观测。
For getStrataTable, a data.frame describing the strata and containing the stratum sizes.
对于getStrataTable,data.frame描述的地层和地层大小。
For getStratumSizes, a numeric vector of the stratum sizes.
对于getStratumSizes,一个数值向量的地层大小。
For getStratumValues, a numeric vector giving the stratum number for each observation.
对于getStratumValues,一个数字向量,层数为每个观测。
