描述----------Description----------

This function takes object of class MAList and it re-orders and filters clones based on their mapping information and proportion missing. It also average duplicated clones and imputes missing values for clones that are still NA after the filtering step. Note that imputation will only take place if duplicated clones are removed.
此功能类MAList“重新订购,并根据自己的映射信息和失踪比例过滤器克隆的对象。它还平均重复克隆和责难失踪仍然后过滤步骤NA克隆值。请注意,归集只会发生,如果重复克隆被删除。


用法----------Usage----------


processCGH(input, maxChromThreshold = 22, minChromThreshold = 1,
           method.of.averaging = NULL, ID = "ID", prop.missing = 0.1)



参数----------Arguments----------

参数:input
Object of class MAList or RGList
对象的类MAList或RGList


参数:maxChromThreshold
Chromosomes are ordered and numbered as usual, except for X and Y chromosome, which in for Homo sapiens genome have numbers 23 and 24 respectively, in for Mus musculus 20 and 21, etc. Remove chromosomes from segmentation analysis which are greater than this value.
像往常一样的染色体排序和编号,除X和Y染色体,在智人基因组有23日和24日的数字分别为20和21小家鼠,等删除分割分析染色体是大于这个值。


参数:minChromThreshold
Chromosomes are ordered and numbered as usual, except for X and Y chromosome, which in for Homo sapiens genome have numbers 23 and 24 respectively, in for Mus musculus 20 and 21, etc. Remove chromosomes from segmentation analysis which are lower than this value.
像往常一样的染色体排序和编号,除X和Y染色体,在智人基因组有23日和24日的数字分别为20和21小家鼠,等删除分割分析染色体是低于此值。


参数:method.of.averaging
If left as the default no combining of replicate spots takes place. Otherwise this should specify a function which takes a vector of duplicates and combines them into a single value.
如果保留为默认的无复制点相结合的发生。否则,这应该指定一个函数,它接受了重复的向量,并把它们结合成一个单一的值。


参数:ID
Name of column in RG\$genes corresponding to the clone names. For most data the default will work, however for affy data the value for ID should be "CloneName"
RG\$genes对应的克隆名称的列名。对于大多数数据默认会的工作,但是,对于affy数据的ID值应该是"CloneName"


参数:prop.missing
For each probe the proportion of NA's is calculated, and the probe is kept for further analysis if the proportion of NA's is less than missing.prop
NA的比例计算每个探针,探针被保留作进一步的分析,如果NA的比例不到missing.prop


值----------Value----------

Object of class SegList
对象类SegList
