ElbowPlot | R Documentation |

Plots the standard deviations (or approximate singular values if running PCAFast) of the principle components for easy identification of an elbow in the graph. This elbow often corresponds well with the significant dims and is much faster to run than Jackstraw

```
ElbowPlot(object, ndims = 20, reduction = "pca")
```
