How to use knitr from command line with Rscript and command line argument?

knitr, r

Solution

I do not see why this is not possible. Here is `my_code.R`:

commandArgs(TRUE)

And I simply run

Rscript -e "library(knitr); stitch('my_code.R')" --args foo bar whatever=blabla

I get the output

It seems you did not use double quotes correctly in your original attempt. It should be

Rscript -e "library(knitr); stitch('my_code.R')" --args arg1=test.txt

Problem

I have an R code `my_code.R` which takes in an argument a file `test.txt`. I can use: ``` Rscript -e my_code.R test.txt ``` and run the script, but i want to use stitch() from knitR to generate the report of the script in pdf/tex. I have trolled around stack overflow and used following suggestions, but didn't get any results: ``` Rscript -e "library(knitr);knit('my_code.R "-args arg1=test.txt" ')" Rscript -e "knitr::stitch('my_code.R "-args arg1=test.txt"')" ``` Here is another similar discussion on what i want (link), but with option for adding argument(s).
