This function is used to preprocess matrix of read counts to only keep genes with a certain number of nonzero entries.
filter_counts(counts, perc.zero = 0.1)
| counts | A non-negative integer matrix of scRNA-seq raw read counts. The rows of the matrix are genes and columns are samples/cells. |
|---|---|
| perc.zero | A numeric value between 0 and 1 that represents the proportion of zeros per gene in the processed dataset. |
An object of class Matrix with genes removed if
they have more than perc.zero zeros.
