editrules (version 2.0-3)

editrules: Retrieve readables editrules from an editmatrix

Description

editrules returns a data.frame describing the editrules in editmatrix x. This data.frame can be used to store the editrules in a readable format, so that the editrules can be maintained and documented.

Usage

editrules(x)

Arguments

x

editmatrix or matrix object

Value

• data.frame with information on all edit rules / constraints

Details

The editmatrix function can use the output of editrules to create an editmatrix.

If x is a normal matrix, the matrix will be coerced to an editmatrix. The columns of the matrix are the variables and the rows are the edit rules (constraints).

Examples

E <- editmatrix(c( "x+3*y == 2*z"
                 , "x > 2")
                 )
print(E)
                 
# get editrules, useful for storing and maintaining the rules external from your script
editrules(E)
                 
# get coeficient matrix of inequalities
getA(E)

# get augmented matrix of linear edit set
getAb(E)

# get constants of inequalities (i.e. c(0, 2))                
getb(E)

# get operators of inequalities (i.e. c("==",">"))
getOps(E)

# get variables of inequalities (i.e. c("x","y","z"))
getVars(E)

# isNormalized
isNormalized(E)

#normalized E
E <- normalize(E)
E

# is het now normalized?
isNormalized(E)
