I’m trying to run GAMS from the R console. However, when I try to install the pacakge Gamstransfer, I always get the message that it is not availbale for the newest R version:
“Warning in install.packages :
package ‘C:\GAMS\41\apifiles\R\gamstransfer\source\gamstransfer_r.tar.gz’ is not available for this version of R”
I’m using R version 4.2.2
Does Gamstransfer simply not run with this version of R? With which version of R does it run?
Are you trying to use R console under RStudio? If you are, then can you try the same thing separately outside R studio (from command prompt → R )?
What happens if you try to install the binary package?
install.packages(“C:/GAMS/41/apifiles/R/gamstransfer/binary/gamstransfer.zip”, type=“biinary”)
I can confirm that it is supposed to work on R 4.2.2.
If none of the above work,
can you please provide the exact command that you run?
which version of GAMS do you have on your computer? 41.0, 41.1,…41.5?
can you provide the output of sessionInfo() and the output of .libPaths()?
I tried this on my Windows 11 machine, and I get gamstransfer installed on R 4.2.2 without a problem. I did this in RStudio:
RStudio 2022.12.0+353 “Elsbeth Geranium” Release (7d165dcfc1b6d300eb247738db2c7076234f6ef0, 2022-12-03) for Windows

Here’s the log of the installation, with sessionInfo() also. This sort of output is helpful to anybody (including you) troubleshooting a problem.
