Does make.dt missmatches documents to meta-data when prepDocuments removed documents?

[luispabreu]

Sometimes, after running prepDocuments, some of the original documents are removed.

Then, when running make.dt, I get the following warning:

Warning messages:
1: In as.data.table.list(x, keep.rownames = keep.rownames, check.names = check.names, :
Item 1 has 3168 rows but longest item has 3176; recycled with remainder.
2: In as.data.table.list(x, keep.rownames = keep.rownames, check.names = check.names, :
Item 2 has 3168 rows but longest item has 3176; recycled with remainder.

I'm unsure if this warning means that the document-topic loadings (theta) are mismatched with the metadata
