Select_genes {TFEA.ChIP}R Documentation

Extracts genes according to logFoldChange and p-val limits

Description

Function to extract Gene IDs from a dataframe according to the established limits for log2(FoldChange) and p-value. If possible, the function will use the adjusted p-value column.

Usage

Select_genes(GeneExpression_df, max_pval = 0.05, min_pval = 0,
  max_LFC = NULL, min_LFC = NULL)

Arguments

GeneExpression_df

A data frame with the folowing fields: 'Gene', 'pvalue' or 'pval.adj', 'log2FoldChange'.

max_pval

maximum p-value allowed, 0.05 by default.

min_pval

minimum p-value allowed, 0 by default.

max_LFC

maximum log2(FoldChange) allowed.

min_LFC

minimum log2(FoldChange) allowed.

Value

A vector of gene IDs.
