Rglpk_read_file {Rglpk} | R Documentation |
High level R interface to the MPS and CPLEX\_LP reader of the GNU Linear Programming Kit (GLPK).
## MPS file reader Rglpk_read_file(file, type = c("MPS_fixed", "MPS_free", "CPLEX_LP", "MathProg"), ignore_first_row = FALSE, verbose = FALSE) ## print method ## S3 method for class 'MP_data_from_file' print(x, ...)
file |
a character specifying the relative or absolute path to the model file. |
type |
a character specifying the file format. This can be either
|
ignore_first_row |
a logical indicating whether the first row of
the model file should be ignored or not.
Default: |
verbose |
a logical for turning on/off additional solver output.
Default: |
x |
an object of class |
... |
further arguments passed on to the print method. |
Rglpk_read_file()
takes the path to a file as an
argument and calls GLPK's file reader. The description of the linear or
mixed integer linear program is returned as an object of class
"MP_data_from_file"
.
Rglpk_read_file()
returns the specification of a mixed integer
linear program defined in file
as an object of class
"MP_data_from_file"
.
