addPrefix {TimiRGeN} | R Documentation

## addPrefix

### Description

Adds 'miR_' or 'mRNA_' genetypes to colnames of dataframes. Resulting colnames should be in the following naming system: 'genetype_timepoint.resulttype'. This function is essential for separate analysis of miR-mRNA DE data. If using the combined analysis, there is no need to use addPrefix.

### Usage

    addPrefix(MAE, gene_df, prefixString = '')

### Arguments

`MAE` | MultiAssayExperiment to store output of addPrefix. It is recommended to use the MAE object which stores output from startObject.
`gene_df` | Dataframe of mRNA or miR results from differential expression analysis. Will be stored as an assay within the MAE used in the startObject function.
`prefixString` | Prefix to be added e.g. "miR" or "mRNA".

### Value

Dataframe which has a specific prefix infront of each column name. Will be stored as an assay in the input MAE.

### Examples

    data(mm_miR)

    data(mm_mRNA)

    MAE <- startObject(miR = mm_miR, mRNA = mm_mRNA)

    MAE <- addPrefix(MAE = MAE, gene_df = assay(MAE, 1),
                     prefixString = "miR")

    MAE <- addPrefix(MAE = MAE, gene_df = assay(MAE, 2),
                     prefixString = "mRNA")
