Please find the ggplot2 heat map demo. pheatmap is also a very good option for heatmap generation in R. However, 4311 rows is a very high number and you can set top 50/100 to show in heatmap.

Though ggplot can output heatmap, but please consider using dedicated libraries such as complexheatmap, pheatmap etc.

There are really plenty of posts on heatmapping. For pure ggplot2 try e.g. https://github.com/XiaoLuo-boy/ggheatmap. Another package beyond those mentioned already would be ComplexHeatmap.
