how to change the UMAP use in the dimplot and feature plot
Try this:

library(Seurat)
pbmc_small &lt;- RunUMAP(pbmc_small, dims = 1:10, reduction = "pca", n.components = 5)

names(pbmc_small[["umap"]])
#&gt; [1] "UMAP_1" "UMAP_2" "UMAP_3" "UMAP_4" "UMAP_5"

# plot
DimPlot(pbmc_small, reduction = "umap", dims = c(4, 5))




This should work with Seurat version 3.1.5

packageVersion("Seurat")
#&gt; [1] '3.1.5'
