Changes in version 1.2.7 2013-05-23

• added functions setColsNamesGLPK(), setRowsNamesGLPK()

Changes in version 1.2.6 2013-02-12

• prints the version number of GLPK on startup

• removed argument check from function loadMatrixGLPK

• if compiled with –enable-chkargs [which is the default]), arguments to GLPK API functions containing GLPK constants or row and column indices are checked more carefully

• very basic support for the GLPK callback routine

Changes in version 1.2.4 2012-07-06

• inconsistent inputs to loadMatrixGLPK will not longer stop the running R session

• new argument check to function loadMatrixGLPK: if set to TRUE (and glpkAPI compiled with –enable-chkargs [which is the default]), other arguments to loadMatrixGLPK will be reviewed in terms of vector length and valid row and column indices, before changing the problem object

• functions setMatRowGLPK and getMatRowGLPK can use vectors returned by getMatRowGLPK and getMatColGLPK respectively

Changes in version 1.2.3 2012-04-20

• bugfix in ‘configure.ac’ when compiling with R32

Changes in version 1.2.2 2012-03-27

• renamed glpkPtr method isNULLpointer to isNULLpointerGLPK

• renamed glpkPtr method pType to glpkPtrType

• renamed glpkPtr method ptr to glpkPointer

Changes in version 1.2.1 2012-03-15

• class glpkPtr does not extend externalptr (not allowed in R version <= 2.14)

• method show for objects of class glpkPtr

• fixed a bug in ‘init.c’: number of arguments to mplAllocWksp was wrong

• added methods isGLPKpointer, isNULLpointer and isTRWKSpointer for objects of class glpkPtr

• make use of glp_error_hook in ‘glpkAPI.c’ in order to prevent GLPK exiting abnormal and so terminating the running R session

• check arguments for row and column indices (i and j) if they fit to the given problem object (again: prevent GLPK from terminating the running R session)

Changes in version 1.2.0 2012-02-14

• exported API-functions are registered

• class glpkPtr extends externalptr

• file ‘c2r.map’ in ‘inst/’: mapping of filenames between C API and glpkAPI, run

  c2r <- system.file(package = "glpkAPI", "c2r.map")
  source(c2r)
        

  in order to use original function names of the GLPK C API.
