define the set of genes to compute the percentage for |

which mode.slot to take the values for computing the percentage from |
multiply.by.100 |
if TRUE, compute percentage values, otherwise fractions between 0 and 1 |
Genes can be referred to by their names, symbols, row numbers in the gene table, or a logical vector referring to the gene table rows.
To refer to data slots, the mode.slot syntax can be used: Each name is either a data slot, or one of (new,old,total) followed by a dot followed by a slot. For new or old, the data slot value is multiplied by ntr or 1-ntr. This can be used e.g. to filter by new counts.
