gEcon package

Please note that gEcon is NOT DISTRIBUTED THROUGH CRAN. You have to download the .tag.gz (source, Linux / Un*x) or .zip (Windows), save it on your disk, and install gEcon package from this file.

Download version 1.2.2 from R-forge

gEcon 1.2.2 is fully compatible with R-4.3.0.

From R version 3.4.0 on, JIT compilation of functions is enabled. This means that functions determining steady state/equilibrium and perturbation matrices are compiled by R before being invoked. For larger models, the compilation may take some time or can even make R freeze. If you encounter any problems running larger models, enable the option output R Rcpp. See the note in Language section of the Users' guide about the performance of JIT and C++ compilers and their outputs.
