rmarkdown::run directly displayed in the web browser?

Question

I try to run a Rmd file (rmarkdown::run, because some shiny code) from R studio directly on the web browser and I cannot find the way.

I tried this solution: Do not open RStudio internal browser after knitting

but I don't know why it does not work for me. In any case, I was looking for a more "universal" solution, like an option of the function "run". When I look at the help, I can clearly see that: https://www.rdocumentation.org/packages/rmarkdown/versions/1.8/topics/run

Unlike render, run does not render the document to a file on disk. In most cases a Web browser will be started automatically to view the document; see launch.browser in the runApp documentation for details.

so I tried:

rmarkdown::run("TCD.CleanR.Rmd", launch.browser = TRUE)

Error in rmarkdown::run("TCD.CleanR.Rmd", launch.browser = TRUE) : 
  argument inutilisé (launch.browser = TRUE)

(sorry for the french :D: meaning unused argument)

I don't understand why it does not work ???

Does someone has an idea?

Thanks a lot in advance :)

It means that the argument provided does not match any of the arguments used by the function.

launch.browser is not an argument of rmarkdown::run(), it is actually an argument of shiny::runApp(). It can be passed through rmarkdown::run() by using shiny_args like so:

rmarkdown::run("TCD.CleanR.Rmd", shiny_args = list(launch.browser = TRUE))

rmarkdown::run directly displayed in the web browser?
