FeaturePlot of Seurat Metadata
Say I have a Seurat object called seur whose metadata includes a column named "count" (list of doubles) that displays how many time a certain cell appears. I want to use the FeaturePlot tool to plot the counts on my UMAP so I can see where the high counts are via the color gradient.
Yet, when I do:
FeaturePlot(seur, features = "count")
I get the error:
count.Error in if (unique.feature.exp == 0) { :
missing value where TRUE/FALSE needed
How do I solve this error and/or correctly use FeaturePlot?
Solution
It should work, check you have Seurat 3 or Seurat 4, I am on using Seurat_3.2.2 below:
library(Seurat)
seur = pbmc_small
eur$count = rpois(ncol(seur),5)
FeaturePlot(seur,features="count")
