Function to fit the Subtype Clustering Model
功能,以适应亚型聚类分析模型
译者:生物统计家园网 机器人LoveR
描述----------Description----------
This function fits the Subtype Clustering Model as published in Desmedt et al. 2008 and Wiarapati et al. 2008. This model is actually a mixture of three Gaussians with equal shape, volume and variance (see EEI model in Mclust). This model is adapted to breast cancer and uses ESR1, ERBB2 and AURKA dimensions to identify the molecular subtypes, i.e. ER-/HER2-, HER2+ and ER+/HER2- (Low and High Prolif).
此功能符合亚型聚类分析模型的,作为发表在Desmedt等。 2008年和Wiarapati等。 2008年。这种模式实际上是一个三高斯与同等形状,体积和方差(见EEI在Mclust模型)的混合物。这种模式适用于乳腺癌和使用ESR1,ERBB2和AURKA尺寸来确定分子亚型,即ER-/HER2-中,HER2 + ER + / HER-2(低和高增殖)。
用法----------Usage----------
subtype.cluster(module.ESR1, module.ERBB2, module.AURKA, data, annot,
do.mapping = FALSE, mapping, do.scale = TRUE, rescale.q = 0.05,
model.name = "EEI", do.BIC = FALSE, plot = FALSE, filen, verbose = FALSE)
参数----------Arguments----------
参数:module.ESR1
Matrix containing the ESR1-related gene(s) in rows and at least three columns: "probe", "EntrezGene.ID" and "coefficient" standing for the name of the probe, the NCBI Entrez Gene id and the coefficient giving the direction and the strength of the association of each gene in the gene list.
行和至少三列矩阵包含的的ESR1相关基因(S):“探针”,“EntrezGene.ID”和“系数”为探针,在NCBI Entrez基因ID名称的地位和系数给人的方向和强度的基因列表中的每个基因的关联。
参数:module.ERBB2
Idem for ERBB2.

Matrix of gene expressions with samples in rows and probes in columns, dimnames being properly defined.
矩阵中的行和列的探针样品的基因表达,dimnames被正确定义。
参数:annot
Matrix of annotations with at least one column named "EntrezGene.ID", dimnames being properly defined.
矩阵至少有一列名为“EntrezGene.ID”的注释,dimnames被正确定义。
参数:do.mapping
TRUE if the mapping through Entrez Gene ids must be performed (in case of ambiguities, the most variant probe is kept for each gene), FALSE otherwise.
TRUE如果通过Entrez基因ID的映射必须执行(含糊不清的情况下,每个基因保存最变种探针),FALSE否则。
参数:mapping
Matrix with columns "EntrezGene.ID" and "probe" used to force the mapping such that the probes are not selected based on their variance.
列“EntrezGene.ID”和“探针”使用强制映射探针没有被选中,根据其方差矩阵。
参数:do.scale
TRUE if the ESR1, ERBB2 and AURKA (module) scores must be rescaled (see rescale), FALSE otherwise.
TRUE如果ESR1,ErbB2和AURKA(模块)的成绩必须重新调整(见rescale)FALSE否则。
参数:rescale.q
Proportion of expected outliers for rescaling the gene expressions.
重新调整基因表达的预期离群的比例。
参数:do.BIC
TRUE if the Bayesian Information Criterion must be computed for number of clusters ranging from 1 to 10, FALSE otherwise.
TRUE如果必须为数字聚类从1到10不等,FALSE否则计算贝叶斯信息准则。
参数:model.name
Name of the model used to fit the mixture of Gaussians with the Mclust from the mclust package; default is "EEI" for fitting a mixture of Gaussians with diagonal variance, equal volume, equal shape and identical orientation.
使用适合从mclust包Mclust的混合高斯模型,默认是“协作计划”对角线差异,同等体积,同等形状和相同的方向拟合的高斯混合的名称。
参数:plot
TRUE if the patients and their corresponding subtypes must be plotted, FALSE otherwise.
TRUE如果病人及其相应的亚型,必须绘制,FALSE否则。
参数:filen
Name of the csv file where the subtype clustering model must be stored.
csv文件必须存储亚型聚类分析模型的名称。
参数:verbose
TRUE to print informative messages, FALSE otherwise.
TRUE打印翔实的消息,FALSE否则。
