\input{folder/file.tex} command in LaTeX fetches the text in the file from the folder. When the main file is run, all the text from file.tex is compiled and included.

Rmd - desired output

I am using R Markdown for my project. I desire to develop and document different topics in different files.

I want to have the following directory structure:

main.Rmd
main_directory
        file1.Rmd
        file2.Rmd
    figures
    read_me
Explored pathways
I have explored the following routes to achieve this.
As suggested in Link 1
sys.source(file = file.path(getwd(), "main_directory", 
                        "code", 
                        "file1.r"))
Here, the code text is not included in the output HTML knit from the Rmd.
As suggested in Link 2
```{r, child=file.path(getwd(), "main_directory", "code", "file1.Rmd"}
It led to the following error:
Error: attempt to use zero-length variable name

As suggested in Link 3
```{r}
includeMarkdown(file.path(getwd(), "main_directory", "code", "file1.Rmd"))
It also led to the following error:
Error: attempt to use zero-length variable name
Question: How to include the Rmd code into main file similar to LaTeX input
The equivalent of the LaTeX \input{"/path/to/file"} is:
```{r include=TRUE, echo=FALSE, results="asis"}
library(readr)
cat(readr::read_file("/path/to/file"))
For many input files you can consider loading readr at the beginning together with the definition of some input_myfile() function. I hope this helps!
