error for calculate cluster expression

[mcornwell1957]

Hi Igor,
small thing - in the calculate_cluster_expression function it throws this error:

Error in rownames_to_column(., "gene") : is.data.frame(df) is not TRUE
Calls: calculate_cluster_expression -> %>% -> arrange -> rownames_to_column -> stopifnot
Execution halted

and its because the cluster_avg_exp (or sample_avg_exp) isnt a dataframe (its a matrix)

easily fixed by wrapping it in a data.frame - but it bugs and stops if you dont do this for me.

cluster_avg_exp = data.frame(cluster_avg_exp %>% round(3)) %>% rownames_to_column("gene") %>% arrange(gene)

Thank you for creating this incredibly useful and functional tool!!

Thanks for reporting!

Are you using Seurat 4? This may have been one of the changes.

Ah. yes, from SessionInfo():

SeuratObject_4.0.0 Seurat_4.0.1

So thats probably it, feel free to disregard if not applicable yet.
Thanks again for making the tool though - seriously, its awesome and does a LOT of heavy lifting
