Error happens when you try to execute command ENV["R_HOME"]

Hi Everyone I am using Julia in R Studio. I have encountered the problem of with installing julia.setup(Install=True). This synatax creat error. Please see them below in picture.
I would appreciate your suggestion.

I am not sure what the issue is, but a good first step in debugging would be to follow the suggestion in the error message. I.e. have you checked that your julia installation works on its own, before trying to connect it to R? Checking that would let you know where to proceed with further debugging and it will probably provide you with more useful error messages.

Thank you kindly for your response. Will you specify the type of test that could be used to see it is working or not. I am new to julia thus not clear about this.

Look I follow this procedure to update the path.
I insert the output of R.home() in terminal in julia as EVN[R/HOME] = “output()” and it run without any problem. But I encountered problem with running Base.include(Main,“C:/Users/PC/AppData/Local/R/win-library/4.3/JuliaCall/julia/setup.jl”) in Julia.
Please see their problem…

After this I suppose to run the Julia_setup() as per procedure…
