Generate Correlation Heatmaps Web App
How to make a correlation heatmap in a free alternative to Excel and GraphPad Prism.
Upload your data as a CSV file and keep the variables arranged in columns. If the file includes a header row, enable the header option in the app. You can adjust decimal and column separators if needed.
The app supports a “pretty” correlation heatmap and a more regular heatmap style, and it can also calculate the number and percentage of correlating pairs.
The heatmap tool is based on R packages including pheatmap and heatmap.2. It can also calculate the total number of datapoints over a threshold, which is useful for estimating overall sample activity.
The shared statistics section also includes Mann-Whitney U test, Welch t-test, paired t-test, ANOVA followed by Tukey HSD, and Kruskal-Wallis tests.
The app is based on R and Shiny and is hosted through shinyapps.io.
