描述----------Description----------
Create MA plots using a reference array (if one channel) or using channel2 as reference (if two channel).
创建主图使用一个参考阵列(如果一个通道),或使用作为参考(如果两个通道)通道。
用法----------Usage----------
MAplot(object, ...)
## S4 method for signature 'FeatureSet'
MAplot(object, what=pm, transfo=log2, groups,
refSamples, which, pch=".", summaryFun=rowMedians,
plotFun=smoothScatter, main="vs pseudo-median reference chip",
pairs=FALSE, ...)
## S4 method for signature 'TilingFeatureSet'
MAplot(object, what=pm, transfo=log2, groups,
refSamples, which, pch=".", summaryFun=rowMedians,
plotFun=smoothScatter, main="vs pseudo-median reference chip",
pairs=FALSE, ...)
## S4 method for signature 'PLMset'
MAplot(object, what=coefs, transfo=identity, groups,
refSamples, which, pch=".", summaryFun=rowMedians,
plotFun=smoothScatter, main="vs pseudo-median reference chip",
pairs=FALSE, ...)
## S4 method for signature 'matrix'
MAplot(object, what=identity, transfo=identity,
groups, refSamples, which, pch=".", summaryFun=rowMedians,
plotFun=smoothScatter, main="vs pseudo-median reference chip",
pairs=FALSE, ...)
## S4 method for signature 'ExpressionSet'
MAplot(object, what=exprs, transfo=identity,
groups, refSamples, which, pch=".", summaryFun=rowMedians,
plotFun=smoothScatter, main="vs pseudo-median reference chip",
pairs=FALSE, ...)
参数----------Arguments----------
参数:object
FeatureSet, PLMset or ExpressionSet object.
FeatureSet,PLMset或ExpressionSet对象。
参数:what
function to be applied on object that will extract the statistics of interest, from which log-ratios and average log-intensities will be computed.
功能将适用于object,将提取感兴趣的统计,从数比和平均log强度计算。
参数:transfo
function to transform the data prior to plotting.
功能改造前的数据来绘制。
参数:groups
factor describing groups of samples that will be combined prior to plotting. If missing, MvA plots are done per sample.
描述样品前将结合到策划组的因素。如果缺少,MVA图每样做。
参数:refSamples
integers (indexing samples) to define which subjects will be used to compute the reference set. If missing, a pseudo-reference chip is estimated using summaryFun.
整数(索引样本),以确定哪些科目将被用来计算参考集。如果失踪,估计伪参考芯片使用summaryFun。
参数:which
integer (indexing samples) describing which samples are to be plotted.
整数(索引样本),说明该样品是要绘制。
参数:pch
same as pch in plot
同样的pchplot
参数:summaryFun
function that operates on a matrix and returns a vector that will be used to summarize data belonging to the same group (or reference) on the computation of grouped-stats.
矩阵的功能,操作和返回一个向量,将属于同一组的分组统计计算(或引用)的汇总数据。
参数:plotFun
function to be used for plotting. Usually smoothScatter, plot or points.
函数被用于绘图。通常是smoothScatter,plot或points。
参数:main
string to be used in title.
字符串要使用的标题。
参数:pairs
logical flag to determine if a matrix of MvA plots is to be generated
逻辑标志来确定矩阵如果MVA图的是要产生
参数:...
Other arguments to be passed downstream, like plot arguments.
其他参数可以通过下游,像plot论据。
Details
详情----------Details----------
MAplot will take the following extra arguments:
MAplot将采取以下额外的参数:
subset: indices of elements to be plotted to reduce impact of plotting 100's thousands points (if pairs=FALSE only);
subset:要绘制绘制100的数千点,以减少影响(元素指标,如果对= FALSE,只);
span: see loess;
span:看到loess;
family.loess: see loess;
family.loess:看到loess;
addLoess: logical flag (default TRUE) to add a loess estimate;
addLoess:逻辑标志(默认为true),添加黄土估计,;
parParams: list of params to be passed to par() (if pairs=TRUE only);
parParams:列表中的params要传递给杆()(= TRUE,如果对);
