AMPL models by Håkan Kjellerstrand

rampl's Issues

A typo in 'rAMPL/docs/source/getting-started.rst'

Thanks for the nice AMPL R API :D
The following line of code to add AMPL binary location to 'PATH' used ';' as the separator whereas the default separator for PATH on Unix is ':'. This raises “AMPL could not be started” error when creating AMPL class later on.

 Sys.setenv(PATH = paste(Sys.getenv("PATH"), "full path to the AMPL installation directory", sep = ";"))

Compatibility with ROI package models?

Is it possible to read/transfer a model created with the ROI package to rAMPL?

rampl_reading_data_defined_in_R_through_tables

Hello,

I need some help regarding the link between ampl and R;

All my data is already prepared in tables in R.

I was wondering if these data can be directly read by ampl code through the same R code, where I defined the inputs as tables.

Thank you,
