Help learning how to make a heatmap with my bulk seq data

Hello! I am looking for help to learn how to create a clustered heatmap with my bulk sequencing data, using R. Specifically, I want to highlight certain genes or proteins that might be represented among the data. This will involve finding patterns and trends that might be useful in understanding various aspects of my data. This will require creating a visualization of the data that is both easy to read and visually stunning. If you have knowledge of R and are experienced in creating heatmaps, I would love to hear from you! Only want to depict top 100 up and downregulsted genes but I'm struggling.
