Hi, I tried your code but still does not work. When I tried the

install.packages(“rstan”)

the result is as below:

Warning in install.packages :
‘lib = “C:/Program Files/R/R-4.2.2/library”’ is not writable
Warning in install.packages :
‘lib = “C:/Program Files/R/R-4.2.2/library”’ is not writable
Warning in install.packages :
cannot create dir ‘C:\Users\R\win-library\4.0R_LIBS_USER = C:\Users’, reason ‘Invalid argument’
Error in install.packages : unable to create ‘C:/Users/R/win-library/4.0R_LIBS_USER = C:/Users/R/win-library/4.0’

Kindly advise?
