描述----------Description----------
Calculate trimmed and/or weighted means of groups of rows in a given data matrix.
一个给定的数据矩阵中的行组计算修剪和/或加权方式。
用法----------Usage----------
combineData(x, y, w, ...)
参数----------Arguments----------
参数:x
a numeric matrix containing the values whose trimmed and/or weighted mean is to be computed. Each column is treated independently.
数字矩阵包含值的修剪和/或加权平均计算。每一列被视为独立。
参数:y
a vector describing the discrete groups used to divide the elements of x. If y is missing then all elements of x are handled together.
向量描述用来除以x的元素的离散组。如果缺少y是x的所有元素一起处理。
参数:w
a matrix of weights the same dimensions as x giving the weights to use for each element of x. If w is missing then all elements of x are given the same weight.
重量为x的重量,使用x的每个元素的尺寸相同的矩阵。如果w丢失,那么x的所有元素都给予同样的重量。
参数:...
Arguments to be passed to methods (see combineData-methods):
被传递到方法的参数(见combineData-methods):
trimthe fraction (0 to 0.5, default is 0) of observations to be trimmed from each group of rows in x according to y.
trim意见分数(0至0.5,默认为0),从每一组行修剪,在x根据y。
na.rmlogical; if TRUE, missing values are removed from x and y and z. If FALSE any missing values cause an error.
na.rm逻辑;如果TRUE,缺失值从x和y和z删除。如果FALSE任何遗漏值导致错误。
element which element of AssayData to use for a given ExpressionSet input (default is "exprs")
element元素AssayData使用一个给定的ExpressionSet输入(默认为"exprs")
feature.group which element of featureData to use as binning variable (default is NULL). Can be a character matching varLabel or simply an integer indicating which feature to choose. See getFeatures.
feature.groupfeatureData作为分级变量使用(默认为NULL)的元素。可以是一个匹配varLabel“或只是一个整数,指示功能选择的字符。看到getFeatures。
element.weight which element of AssayData to use for a given ExpressionSet input. If NULL (default), weighting is not performed.
element.weightAssayData使用一个给定的ExpressionSet输入元素。如果NULL(默认),比重没有进行。
feature.weight which element of featureData to use as weighting variable (default is NULL). Can be a character matching varLabel or simply an integer indicating which feature to choose. See getFeatures.
feature.weightfeatureData使用加权变量(默认是NULL)元素。可以是一个匹配varLabel“或只是一个整数,指示功能选择的字符。看到getFeatures。
samples which samples to use as data. Can be a vector of characters matching sample names, integers indicating which samples to choose, or a mixture of the two. If NULL (default), all samples will be used.
samples样品使用的数据。可以是一个矢量字符匹配样本的名称,表示样本选择的整数,或两者的混合物。如果NULL(默认),所有样品将使用。
\dots other arguments not handled at this time.
\dots其他参数没有在这个时间处理。
值----------Value----------
Returns a matrix of combined numerical data, where each row represents the summary of a group of elements from the corresponding column in x.
返回一个联合的数值数据的矩阵,每一行代表一组从x中的相应列的元素的总结。
注意----------Note----------
Each column in data matrix treated separately.
数据矩阵的每一列分别对待。

#demo(pipeline,package="HELP")[演示(管道,包=“帮助”)]
x <- 1:100
combineData(x,w=x/100)
weighted.mean(x,w=x/100)
y <- sample(c("a","b","c",1:3),size=100,replace=TRUE)
