Heatmaps are a great way visualize a numerical dataset in a matrix form. Basically, a heatmap shows the actual data values as colors. When there is a broad trend in data, like change in data over rows or columns of data, a heat map makes it easy to see the broader trend. In this tutorial,… Continue reading How To Make Heatmaps in R with ComplexHeatmap?

How to Make Heatmaps in R with pheatmap?
Heatmaps are one of the ways to visualize quantitative data in two dimension. Heatmaps show the actual data as colors and can reveal common patterns easily. In R, there are multiple ways to make heatmap starting from data in matrix form. In this post, we will learn how to make simple heatmaps with using pheatmap… Continue reading How to Make Heatmaps in R with pheatmap?
Heatmap from Matrix using ggplot2 in R
Heatmaps are data visualization tool that displays a matrix of data as a matrix of colors. For example, matrix elements with low values will have lighter colors and the elelments with high values will have a darker color. In earlier post we saw examples of making heatmap using ggplot2 in R. However, we assumed that… Continue reading Heatmap from Matrix using ggplot2 in R
How To Make Simple Heatmaps with ggplot2 in R?
Heatmaps visualizes multi-dimensional data as a matrix filled with colors based on their numerical value. For example the portion of matrix with low values will have one color and the portion with high values will have another color. This can help us identify the pattern in the data easily. In this post we will examples… Continue reading How To Make Simple Heatmaps with ggplot2 in R?
