Render Rmarkdown to directory outside R package

I have a R package that generates a RMarkdown html report. The .Rmd file lives in the system library/package directory. I would like to create a function htmlreport() to save the html report to the specified output directory path. In case output_path is not specified the function should give the possibility to browse to the output folder.

After rendering I would also like to open the resulting html report.

I am no sure how to do this. It seems that the path to the output file is always relative to the .Rmd file. How can I achieve this?

htmlreport <- function(output_path = NULL){
 f <- system.file("inst/rmd", "html_report.Rmd", package = "abc")

 if (is.null(outputh_path)) { 
    output_path <- ?? "Choose output folder" ....??
 }

 rmarkdown::render(f, output_dir = output_path) 

 # and open the html report..?
}

output_dir can be any path, not only relative to rmd file.

To select a folder, you can use function choose.dir() in base R package utils or function selectDirectory() in rstudioapi (which means that it will only work if function is launched from rstudio)

To display the html file use function browseURL from base R package utils using url constructed with paste0("file://",<full path of your file using / separator>)
