DGCA (version 1.0.3)

ddcorFindSignificant: Find groups of differentially correlated gene symbols.

Description

Takes a table of differentially correlated genes with respect to one gene in the Gene2 column and returns the a list of vectors with unique, non-NA gene symbols for genes in each of the differentially correlated classes.

Usage

ddcorFindSignificant(ddcor_res, pval_gene_thresh = 0.05, adjusted = FALSE,
  classes = FALSE, geneNameCol = c("Gene1", "Gene2"),
  unique_genes = FALSE, regcor = FALSE)

Value

A list of significantly differentially correlated genes.

Arguments

ddcor_res

The table of differential correlations outputted from ddcor. Expected to have pValDiff or pValDiff_adj columns as well as zScoreDiff, Gene1, +/- Classes columns.

pval_gene_thresh

p-value threshold to call a gene as having significant differential correlation or not. Default = 0.05

adjusted

Logical indicating whether adjusted p-values from the differential correlation table (i.e., column "pValDiff_adj", when adjusted = TRUE) or unadjusted p-values (i.e., column "pValDiff", when adjusted = FALSE) should be used to subset the table into significant and non-significant portions. Default = FALSE

classes

Logical indicator specifying whether individual differential correlation gene classes should be extracted from the table or not. If not, only the zScoreDiff column is used to specify positively or negatively differentially correlated genes between the two conditions. Default = FALSE

geneNameCol

Character vector specifying the name of the columns that are used to extract the gene symbols. Note that the default is c("Gene1", "Gene2"), but this only makes sense in the context of a full DGCA experiment. In the case of a splitSet, you may want to use "Gene1" to avoid counting the splitSet names in all of the categories.

unique_genes

Logical, if TRUE indicates that unique gene symbols from each category compared to the other groups should be chosen prior to GO enrichment analysis.

regcor

Logical specifying whether the ddcorGO analysis should be performed on the results of a regcor data analysis. Note that the classes option is not available in this case.
