object |
Seurat object |
pc.genes |
Genes to use as input for PCA. Default is object@var.genes |
do.print |
Print the top genes associated with high/low loadings for the PCs |
pcs.print |
Number of PCs to print genes for |
pcs.store |
Number of PCs to store |
genes.print |
Number of genes to print for each PC |
use.imputed |
Run PCA on imputed values (FALSE by default) |
rev.pca |
By default computes the PCA on the cell x gene matrix. Setting to true will compute it on gene x cell matrix. |

Additional arguments to be passed to prcomp |
Returns Seurat object with an PCA embedding (object@pca.rot) and gene projection matrix (object@pca.x). The PCA object itself is stored in object@pca.obj[[1]]
