check.mass.balance: Check given biochemical reaction is mass-balanced
In RbioRXN: Process Rhea, KEGG, MetaCyc, Unipathway Biochemical Reaction Data

Description Usage Arguments Value Author(s) Examples

Using molecular formula of reaction participants, check given reaction equation is mass-balanced. Note that some reaction participants don't have molecular formula (e.g., polymer or generic compound), so these reactions cannot be checked.

1 2	check.mass.balance(equation, chemical_table, id_col="chebi", formula_col="formula", direction_type=c(" <=> ", " => ", " <\\?> "))

`equation`	Reaction equation usually from get.rhea.all() or get.metacyc.all() function.
`chemical_table`	Chemial table (data.frame) containing molecular formula
`id_col`	In chemical table, choose the column name which contains chemical ID (usually first column)
`formula_col`	In chemical table, choose the column name which contains molecular formula
`direction_type`	In reaction equation, provide reaction direction symbols. Default value is c(" <=> ", " => ", " <\\?> ")

Character values (not logical)

`TRUE`
`FALSE`
`Not available`
