build_models: Generate a deSet object with full and null models
In edge: Extraction of Differential Gene Expression

Description Usage Arguments Value Author(s) See Also Examples

build_models creates a deSet object. The user inputs the full and null models.

1	build_models(data, cov, full.model = NULL, null.model = NULL, ind = NULL)

`data`	`matrix`: gene expression data.
`cov`	`data.frame`: the covariates in the study.
`full.model`	`formula`: the adjustment and the biological variables of interest.
`null.model`	`formula`: the adjustment variables.
`ind`	`factor`: individuals sampled in the study. Default is NULL. Optional.

# create models
