checking here on my system:

> mypath <- .libPaths(Sys.getenv('R_LIBS_USER'))
> mypath
[1] "C:/Program Files/R/R-3.4.4/library"
> 

in this situation, I need administrator rights to install packages. thus
there may be a wide range of different settings out there in the windows
wild.

---------
There were 50 or more warnings (use warnings() to see the first 50)
Error in file(file, ifelse(append, "a", "w")) : 
  cannot open the connection
Calls: write.csv -> eval.parent -> eval -> eval -> write.table -> file
In addition: Warning message:
In file(file, ifelse(append, "a", "w")) :
  cannot open file '.gscript_tmp_model_output_1300.csv': Permission denied

so maybe I misread the last sentence. ;-)
