Heat map and clustering are used frequently in expression analysis studies for data visualization. Simple clustering and heat map can be produced from the “heatmap” function in R language. However, it has some limitations in producing advanced graphics and is not highly customizable. Thus, we developed an R package heatmap3 which significantly improves the original heatmap by adding more powerful and convenient features and providing a highly customizable interface.
Materials and methods
The heatmap3 package is developed based on the heatmap function in the R language and is completely compatible with it. All the commands and parameters for heatmap can also be used in heatmap3. At the same time, heatmap3 imported many new parameters to provide more powerful features. Heatmap3 also provided a highly customizable interface for users’ own functions so that they can label and annotate the data in the figure very easily.
The heatmap3 package can be accessed freely at github .
