ISAUnique()所属R语言包：eisa
Remove duplicated ISA modules
删除重复的ISA模块
译者：生物统计家园网 机器人LoveR
描述----------Description----------
From a potentially non-unique set of ISA modules remove all modules that are similar to another module that was found earlier.
从潜在的非一套独特的ISA模块，删除所有类似先前发现的另一个模块的模块。
用法----------Usage----------
ISAUnique(data, isaresult, ...)
参数----------Arguments----------
参数：data
An ExpressionSet or ISAExpressionSet object. If an ExpressionSet object is supplied, then it is normalised by calling ISANormalize on it.
ExpressionSet或ISAExpressionSet对象。如果ExpressionSet对象提供的，那么它被调用ISANormalize标准化。
参数：isaresult
An ISAModules object to be filtered.
ISAModules对象进行过滤。
参数：...
Additional arguments, these are passed to the isa.unique function in the isa2 package. See also details below.
额外的参数，这些都传递给isa.uniqueisa2包的功能。看到详情如下。

详情----------Details----------
The ISA algorithm might very well find the same modules from many different input seeds, so the output of the ISAIterate function is usually not unique: many modules are very similar to each other.
在ISA算法很可能来自许多不同的输入种子相同的模块，所以ISAIterate函数的输出通常是不唯一：很多模块是彼此非常相似。
ISAUnique eliminates the duplicates and potentially also the non-convergent modules.
ISAUnique消除重复的和潜在的也非收敛模块。
The work is performed by calling the isa.iterate function in the isa2 package. The following additional arguments can be specified to be passed to this function:
这项工作是通过调用在isa.iterate包isa2功能。以下额外的参数可以指定要传递给此函数：
method Character scalar giving the method to be used to determine if two biclusters are similar. Right now only "cor" is implemented, this keeps both biclusters if their Pearson correlation is less than cor.limit, both for
要使用的方法，以确定是否两个biclusters是类似的方法特征标。眼下只有cor来实现，这使双方biclusters比cor.limit如果他们的Pearson相关，既为
ignore.div Logical scalar, if TRUE, then the divergent
ignore.div逻辑标量，如果TRUE，然后发散
cor.limit Numeric scalar, giving the correlation limit for the
cor.limit数字标，给予相关限制
neg.cor Logical scalar, if TRUE, then the "cor" method considers the absolute value of the
neg.cor标逻辑，如果TRUE，然后cor方法认为的绝对值
drop.zero Logical scalar, whether to drop biclusters that have
drop.zero逻辑标，是否有下降biclusters
值----------Value----------
Another ISAModules object, with unique modules.
另一个ISAModules对象，具有独特的模块。

举例----------Examples----------
library(ALL)
data(ALL)
# Only use a small sample, to make this example finish faster[只使用一个小样本，使这个例子完成得更快]
ALL.normed <- ISANormalize(ALL)[sample(1:nrow(ALL), 1000),]
# Generate seeds and do ISA[生成种子和办赛]
seeds <- generate.seeds(nrow(ALL.normed), count=100)
modules <- ISAIterate(ALL.normed, seeds, thr.feat=3, thr.samp=2)
modules
# Merge the modules[合并模块]
modules2 <- ISAUnique(ALL.normed, modules)
