`filterTaxonMatrix.Rd`

Discard taxa with less than the given minimum number of occurrences.

filterTaxonMatrix( x, minocc = 0, keepSum = FALSE, return.filtered.indices = FALSE )

x | taxon abundance matrix, rows are taxa, columns are samples |
---|---|

minocc | minimum occurrence (minimum number of samples with non-zero taxon abundance) |

keepSum | If keepSum is true, the discarded rows are summed and the sum is added as a row with name: summed-nonfeat-rows |

return.filtered.indices | if true, return an object with the filtered abundance matrix in mat and the indices of removed taxa in the original matrix in filtered.indices |
