Average Over Irregular Replicate Probes
平均不规则复制探针
译者:生物统计家园网 机器人LoveR
描述----------Description----------
Condense a microarray data object so that values for within-array replicate probes are replaced with their average.
凝结一个芯片的数据对象,使阵内复制探针值与它们的平均取代。
用法----------Usage----------
## Default S3 method:[默认方法]
avereps(x, ID=rownames(x))
## S3 method for class 'MAList'
avereps(x, ID=NULL)
## S3 method for class 'EList'
avereps(x, ID=NULL)
参数----------Arguments----------
参数:x
a matrix-like object, usually a matrix, MAList or EList object.
一个矩阵类的对象,通常是一个矩阵,MAList或EList对象。
参数:ID
probe identifier.
探针标识。
Details
详情----------Details----------
A new data object is computed in which each probe ID is represented by the average of its replicate spots or features.
在每个探针ID代表其复制点或功能的平均计算一个新的数据对象。
For an MAList object, the components M and A are both averaged in this way, as are weights and any matrices found in object$other. For an MAList object, ID defaults to MA$genes$ID is that exists, otherwise to rownames(MA$M).
MAList对象,组件M和A都平均在这种方式,是weights和任何矩阵object$other发现。对于MAList对象,ID默认MA$genes$ID是存在的,否则rownames(MA$M)。
EList objects are similar, except that the E component is averaged instead of M and A.
EList对象是类似除E组件的平均值,而不是M和A,。
If x is of mode "character", then the replicate values are assumed to be equal and the first is taken as the average.
x如果模式"character",然后复制值被认为是平等的,首先是采取平均。
值----------Value----------
A data object of the same class as x with a row for each unique value of ID.
同一类的数据对象x一排每个ID的独特价值。
