Hello Stefan,
the GLPK help list received the mail copied below.
As the question is about Rglpk and not about GLPK I guess you should be
able to answer it.
The Rglpk_read_file function lacks correct error handling. Therefore the
whole R session will end if an error occurs in the GLPK library.
Please, use glp_error_hook() to define a hook function which will
gracefully handle errors.
I append an example code.
Best regards
Heinrich Schuchardt
