Let’s carry out K-means clustering in R using some real high-dimensional data. We’re going to work with single-cell RNAseq data in these clustering challenges, which is often very high-dimensional. Commonly, experiments profile the expression level of 10,000+ genes in thousands of cells. fcss hlWebb1 Introduction. In order to aid the interpretation of the clustering results that we covered in the previous section, it is helpful to identify genes that contribute to the separation of cells into those clusters. The main approach to achieve this, is to identify genes that are differently expressed between clusters. friv4school ghost house game
