WebVizDimLoadings ( pbmc, dims = 1:2, reduction = "pca", balanced=TRUE) Yet another approach which provides a pictorial representation. The cells and features are ordered based on the PCA scores. Setting a cell number helps computational efficiency by ignoring the extreme cells which are less informative. WebPCA just gives you a linearly independent sub-sample of your data that is the optimal under an RSS reconstruction criterion. You might use it for classification, or regression, or both, …
