Example tidy expression dataset for heatmap plotting

A small long-format data frame with simulated gene expression values across three samples, intended for use in plot_heatmap examples and tests.

Usage

ex_data_heatmap

A data frame with 9 rows and 10 columns:

external_gene_name: Character. Gene identifier (GeneA–GeneC).
sample: Character. Sample identifier (S1–S3).
expression: Numeric. Simulated expression value.
is_immune_gene: Character. Whether the gene is an immune gene ("yes" or "no").
direction: Character. Expression direction ("up" or "down").
log2fc: Numeric. Log2 fold change.
sample_type: Character. Sample type ("input" or "IP").
condition: Character. Experimental condition ("healthy" or "EAE").
