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.

### Examples

    data('hypoxia',package='TFEA.ChIP')
    Select_genes(hypoxia)
