Get a Subset of Matrix Like Objects
Generate subsets of matrix-like objects.
## S4 method for signature 'modelorg'
shrinkMatrix(X, i = NULL, j = NULL,
tol = SYBIL_SETTINGS("TOLERANCE"))X |
An object treated to be matrix-like. |
i |
A numeric or character vector containing row indices of the matrix
given in argument |
j |
A numeric or character vector containing column indices of the
matrix given in argument |
tol |
A tolerance value. An element X[i, j] of the matrix given in
argument |
signature(X = "modelorg")method to use with objects of class modelorg for
subsets of the stoichiometric matrix. Either argument i or
argument j can be used, not both at the same time. If they are of
type character, they must contain metabolite or reaction id's existing
in the modelorg object. Use i to get the
reactions in which the metabolites given in i participate (the
metabolites given in i will be located in the first rows of the
result). Use j to get all reactions given in j. The method
will remove all non-zero rows and columns from the result.
