Description Usage Arguments Value Examples
Fit glm.nb , add anova to result, add lsm to result.
Before fitting, data
and factors
will be merged by row.names, mismatching rows will be removed.
If formula start with ~, will fit model with each data column of data as respond y.
1 | octopus.glm.nb(formula, data, factors, specs4lsmeans = NULL)
|
formula |
formula |
data |
normalized reads, expecting gene as column, sample as row |
factors |
factors, expecting factor name as column, sample as row |
specs4lsmeans |
specs for lsmeans |
model if formula
has respond y; flattened anova table, lsm table and se table if formula starts with ~.
