The Working directories setting problem

[peikolim]

I try to run this code, but R prompts an error that Error in file(filename, "r", encoding = encoding) :
cannot open the connection
In addition: Warning message:
In file(filename, "r", encoding = encoding) :
cannot open file './functions/fun_model_setup.R': No such file or directory
why this error be prompts? I ran it exactly according to your code

Hello Peikolim

This sounds as though we need to make sure you have the correct directory in R specified, which will also be crucial for the rest of the code to function.

When we run source(paste0(directories$dir_fun, "fun_model_setup.R")) we are pasting in the directory we specified earlier in the code. We try to load in the function from the repository's function folder: ./functions/fun_model_setup.R

However, this assume your directory has already been set to be at HB_CE_microsimulation. If you enter the getwd() function, it should point you there. In my case, getwd() gives me the following directory: "C:/Users/min1/OneDrive - Berner Fachhochschule/Rprojects/HB_CE_microsimulation". But for you, this will be a different directory.

One way to make sure you have the right directory would be open the entire project via the "HB_CE_microsimulation.Rproj" file, which should automatically set the correct directory to wherever you have locally saved this repository.

I hope this helps!
