UMAP, short for "Uniform Manifold Approximation and Projection" is a one of the useful dimensionality reduction techniques like tSNE and PCA. UMAP is non-linear dimension reduction technique and often used for visualizing high-dimensional datasets. In this tutorial, we will learn … [Read more...] about How to make UMAP plot in R

How to Remove Space between Legend at Bottom and x-axis in ggplot2
In ggplot2, we can adjust the position of legend easily. By default, ggplot2 places the legend on the right side of a plot. Using theme() function, we can move the legend to the bottom of or top of the plot. Sometime, you might like to customize the space between legend at bottom … [Read more...] about How to Remove Space between Legend at Bottom and x-axis in ggplot2

Adding percentage labels or count labels to bars in a barplot can help read the barplot quickly. In this tutorial, we will learn how to add labels with percentage symbol on bars in a barplot made with ggplot2 in R. Loading Packages and Dataset Let us get started by loading … [Read more...] about How to add percentage label on bars in barplot with ggplot2
Grouped Boxplots with reproducible jittered data points
In this post we will learn how to make a grouped boxplots with reproducible jittered points. We can make a grouped boxplot with jittered points using position_jitterdodge() function as position argument to geom_point(). Note that using the handy wrapper function … [Read more...] about Grouped Boxplots with reproducible jittered data points
How to make random jittered points reproducible
In this post we will learn how to make a random jitter plots made with ggplot2 reproducible. We have multiple posts on the importance of showing the actual data points while making boxplots/violinplots. One of the ways to avoid overplotting, is to add random jitters on the x-axis … [Read more...] about How to make random jittered points reproducible
