geneDel finds the fluxes corresponding to gene id's.geneDel(model, genes, checkId = FALSE)modelorg.model, or an
integer vector with indices to gene id's in allGenes(model).TRUE, argument genes will be checked wether
it fits to model (e.g. are all genes existing). If set to
FALSE, genes must contain indices of gene id's in
mmodel or NA.geneDel checks for a set of gene id's in gene
which fluxes this set effects.optimizer
