描述----------Description----------
Derives a mask to define a subset of peaksets or sites for a DBA object.
派生出一个面具来定义一个DBA对象peaksets或网站的一个子集。
用法----------Usage----------
dba.mask(DBA, attribute, value, combine='or', mask, merge='or', bApply=FALSE,
peakset, minValue=-1)
参数----------Arguments----------
参数：DBA
DBA object
DBA的对象
参数：attribute
when deriving a peakset mask, attribute to base mask on:
派生peakset面具时，归因于基础面膜：
DBA_ID
DBA_ID
DBA_TISSUE
DBA_TISSUE
DBA_FACTOR
DBA_FACTOR
DBA_CONDITION
DBA_CONDITION
DBA_REPLICATE
DBA_REPLICATE
DBA_CONSENSUS
DBA_CONSENSUS
DBA_CALLER
DBA_CALLER
DBA_CONTROL
DBA_CONTROL
参数：value
when deriving a peakset/sample mask, attribute value (or vector of attribute values) to match.
派生peakset /样品面具时，属性值（或属性值的向量）相匹配。
参数：combine
when deriving a peakset/sample mask, if value is a vector, OR when deriving a site mask, and peaksets is a vector, this is method for combining result of each value:
派生peakset /样品面具时，如果值是一个向量，或派生网站面具时，和peaksets是一个向量，这是每个值的方法相结合的结果：
“or”
“或”
“and”
“和”
“nor”
“也不是”
“nand”
“NAND”
参数：mask
when deriving a peakset/sample mask, this specifies an existing mask to merge with; if missing, create new mask
派生peakset /样品面具时，指定一个现有的的面具合并，如果缺少，创造新的面具
参数：merge
when deriving a peakset/sample mask, and an existing mask is supplied, this speficies the method for combining new mask with supplied mask:
当派生peakset /样品面具，提供现有的面具，这speficies结合提供新的面具面具的方法：
“or”
“或”
“and”
“和”
“nor”
“也不是”
“nand” note: if mask is missing, “nand” results in negative of mask
“NAND”注意：如果缺少掩码，“NAND”面具的负面结果
参数：bApply
when deriving a peakset/sample mask, a logical indicating that a new DBA object with the mask applied will be returned.
派生peakset /样品面具时指出，逻辑与应用的面具新的DBA对象将被退回。
参数：peakset
when deriving a peak/site mask, this specifies a peakset number, or a vector of peakset numbers. The resulting mask will indicate which of the overall sites were called as peaks in this peakset or set of peaksets. If a vector, the masks for each of the peaksets will be combined using the method specified in the combine parameter.
派生一个高峰/网站面具时，指定的peakset号码，或向量peakset数字。产生的面具将显示整体网站呼吁在此peakset或peaksets的一套峰。如果一个向量，为每个peaksets的口罩将合并使用联合收割机参数中指定的方法。
参数：minValue
when deriving a peak/site mask, scores greater than this value will be considered as indicating that the site corresponds to a called peakset.
派生一个高峰/网站面具时，得分大于这个值将被视为显示该网站对应一个名为peakset。
Details
详情----------Details----------
MODE: Derive a a mask of peaksets/samples:
模式：导出的口罩peaksets /样品：
dba.mask(DBA, attribute, value, combine, mask, merge, bApply)
dba.mask（DBA来说，属性，价值，结合面具，合并，bApply）
MODE: Derive a mask of peaks/sites:
模式：导出峰/遗址的面具：
dba.mask(DBA, combine, mask, merge,bApply, peakset, minValue)
dba.mask（DBA的结合起来，面具，合并，bApply，peakset，MINVALUE）
值----------Value----------
either a logical mask, or new DBA object if bApply is TRUE.
无论是逻辑的面具，或新的DBA对象如果bApply为TRUE。
注意----------Note----------
dba automatically generates masks for each unique value of DBA_TISSUE, DBA_FACTOR, DBA_CONDITION, DBA_CALLER, and DBA_REPLICATE. These are accessible using masks field of the DBA object (DBA$masks), and can be viewed using names(DBA$masks).
DBA为独特每个DBA_TISSUE，DBA_FACTOR，DBA_CONDITION，DBA_CALLER的价值会自动生成口罩，DBA_REPLICATE。这些都是使用口罩DBA的对象（DBA的$口罩）领域的访问，可以被视为使用名称（DBA的$口罩）。

举例----------Examples----------
data(tamoxifen_peaks)
# Pre-made masks[预制口罩]
names(tamoxifen$masks)
dba.show(tamoxifen,tamoxifen$masks$MCF7)
# New masks[新口罩]
mcf7Mask = dba.mask(tamoxifen,DBA_TISSUE, "MCF7")
mcf7DerivedMask = dba.mask(tamoxifen,DBA_TISSUE,"TAMR",mask=mcf7Mask)
mcf7Derived = dba(tamoxifen,mcf7DerivedMask)
mcf7Derived
