Error in matrix(ind, nrow = m, ncol = rank, dimnames = dnms) : invalid 'nrow' value (too large or NA)

[njtourtillott]

Hi, I've tried running AUC_buildRankings on my data and I've encountered the following error: Error in matrix(ind, nrow = m, ncol = rank, dimnames = dnms) :
invalid 'nrow' value (too large or NA)

For reference I'm passing in the RNACounts table from my Seurat object (so SO@assays$RNA@Counts).

Would someone be able to explain why this error is occurring and how I would go about fixing it?

Thanks,
Nick
