译者:生物统计家园网 机器人LoveR
描述----------Description----------
Expands result from CGHcall function to CGHcall object.
CGHcall函数到CGHcall对象扩大的结果。
用法----------Usage----------
ExpandCGHcall(listcall,inputSegmented, digits=3, divide=4, memeff = FALSE, fileoutpre="Callobj_")
参数----------Arguments----------
参数:listcall
List object; output of function CGHcall
列表中的对象;输出功能CGHcall
参数:inputSegmented
An object of class cghSeg
一个对象的类cghSeg
参数:digits
Number of decimal digits to be saved in the resulting call object. Allows for saving storage space
被保存在调用对象的小数位数的数目。允许为节省存储空间
参数:divide
Number of batches to divide the work load in. Larger values saves memory, but requires more computing time
一批批英寸较大的值来划分的工作负载,节省内存,但需要更多的计算时间
参数:memeff
When set to TRUE, memory efficient mode is used: results are written in batches to multiple external files. If FALSE, one output object is provided.
当设置为TRUE,高效的内存模式用于分批到多个外部文件的书面结果。如果为FALSE,提供一个输出对象。
参数:fileoutpre
Only relevant when memeff=TRUE. Define prefix for output file names
只有相关=真memeff。定义为输出文件名前缀
Details
详情----------Details----------
This function is new in version 2.7.0. It allows more memory efficient handling of large data objects. If R crashes because of memory problem, we advise to set memeff = TRUE and increase the value of divide. When multiple files are output (in case of memeff=TRUE) the function combine may be used to combine CGHcall objects.
此功能是新的版本2.7.0。它可以更有效地处理大型数据对象的内存。如果R崩溃,因为内存的问题,我们建议设置memeff = TRUE和增加价值的鸿沟。当多个文件输出(memeff = TRUE的情况)功能结合,可用于结合CGHcall对象。
值----------Value----------
An object of class cghCall-class either as one object (when memeff = FALSE) or as multiple objects stored in .Rdata files in the working directory (when memeff = FALSE)
一个类的对象cghCall-class(当memeff为FALSE)作为一个对象或多个对象存储。RDATA工作目录中的文件(当memeff为FALSE)
