### Description

Identify variable genes for dimensionality reduction

### Usage

    keep_variable_transcripts(
      .data,
      .sample = NULL,
      .transcript = NULL,
      .abundance = NULL,
      top = 500,
      log_transform = TRUE
    )

### Arguments

`.data` | A tibble
`.sample` | A character name of the sample column
`.transcript` | A character name of the transcript/gene column
`.abundance` | A character name of the read count column
`top` | An integer. How many top genes to select
`log_transform` | A boolean, whether the value should be log-transformed (e.g., TRUE for RNA sequencing data)
