描述----------Description----------
Plot mean expression values for two sets of samples,
图意味着两套样本表达式的值,
用法----------Usage----------
mnplot (x, expset, group, ...)
ISAmnplot (modules, number, eset, norm = c("raw", "feature", "sample"),
group, ...)
参数----------Arguments----------
参数:x
A character vector, the feature names for which the plot is created.
一个特征向量,特征名称为创建该图。
参数:expset
An ExpressionSet object (Biobase package), or an expression matrix, with row names as feature names.
ExpressionSet对象(Biobase包),或表达矩阵,行名称与功能名称。
参数:eset
An ExpressionSet or ISAExpressionSet object. If an ExpressionSet object is supplied (and the norm argument is not set to "raw"), then it is normalised by calling ISANormalize on it. A subset of eset is selected that corresponds to the features included in modules.
ExpressionSet或ISAExpressionSet对象。如果ExpressionSet对象提供(和norm参数没有被设置为“原始”),然后调用ISANormalize标准化。被选中对应的功能包括在esetmodules的一个子集。
参数:norm
Character constant, specifies whether and how to normalize the expression values to plot. "raw" plots the raw expression values, "feature" the expression values scaled and centered for each feature (=gene) separately and if "sample" is specified then the expression values are centered and scaled separately for each sample.
字符常量,指定是否以及如何标准化的表达式的值来绘制。 “原始”图的原始表达式的值,功能的表达式的值缩放,并为每个功能(基因)分别和“样本”,然后指定表达式的值集中,并调整每个样品分别为中心。
参数:group
A factor that defines two groups to plot one against the other.
定义两组绘制一个对其他的一个因素。
参数:modules
An ISAModules object.
ISAModules对象。
参数:number
A numeric scalar, the number of the module for which the plot is created.
一个数字标量,图创建的模块的数量。
参数:...
Additional arguments, they are passed to the plot function.
额外的参数,它们传递给plot功能。
Details
详情----------Details----------
mnplot plots two group-means against each other, the mean expression of all the specified probes. The two groups are specified as a factor with two levels.
mnplot绘制两条组互相对抗的手段,对所有指定的探针的平均表现。两组被指定为两个层次的一个因素。
ISAmnplot calls mnplot and plots the mean expression of genes in an ISA module, again, for two groups.
ISAmnplot调用mnplot“图平均一个ISA模块中的基因表达,再次为两组。
值----------Value----------
Both functions return invisibly a matrix with two lines, the mean expression values for the two groups, for all the specified genes.
这两个函数返回无形中有两条线,所有指定的基因中,两组的平均表达值矩阵。
