A MODifieR input object produced by one of the |
beta |
User-defined soft thresholding power For method=="tree" it defaults to 0.99. For method=="hybrid" it defaults to 99 maximum of the joining heights on the dendrogram. |
cor_method |
a character string indicating which correlation coefficient (or covariance) is to be computed. One of "pearson" (default), "kendall", or "spearman": can be abbreviated. |
cluster_method |
the agglomeration method to be used. This should be (an unambiguous abbreviation of) one of "ward", "single", "complete", "average", "mcquitty", "median" or "centroid". This applies to hierachical clustering. |
cuttree_method |
Chooses the method to use. Recognized values are "hybrid" and "tree". |
cut_height |
Maximum joining heights that will be considered. |
deepSplit |
For method "hybrid", can be either logical or integer in the range 0 to 4. For method
"tree", must be logical. In both cases, provides a rough control over sensitivity to cluster splitting.
The higher the value (or if |
pamRespectsDendro |
Logical, only used for method "hybrid". If |
minClusterSize |
Minimum cluster size. |
cutHeight |
Maximum joining heights that will be considered. For |
pval_cutoff |
The p-value cutoff to be used for significant co-expression modules (colors) |
dataset_name |
Optional name for the input object that will be stored in the settings object. Default is the variable name of the input object |
DiffCoEx is a method for identifying correlation pattern changes, which builds on the commonly used Weighted Gene Coexpression Network Analysis (WGCNA) framework for coexpression analysis.
diffcoex returns an object of class "MODifieR_module" with subclass "DiffCoEx". This object is a named list containing the following components:
module_genes |
A character vector containing the genes in the final module |
module_colors |
A character vector containing the colors that make up the final disease module |
color_vector |
A named character vector containing the genes as values and the color as name |
settings |
A named list containing the parameters used in generating the object |
