The directory does not not exist

Title is not a typo.

I have created an RMarkdown file and am only trying to render it.

> rmarkdown::render(input = "../models/SUPPLIER_NAME/SUPPLIER_NAME_20190820.Rmd", output_format = "html_document", output_file = "../models/SUPPLIER_NAME/SUPPLIER_NAME_20190820.html")
# Error: The directory '../models/SUPPLIER_NAME') does not not exist.
> file.exists("../models/SUPPLIER_NAME")
# [1] TRUE

Notice the error message is correct, it does "not not" exist. I am speechless.

Are you on a Unix system? Or on Windows?

Can you please also check using dir.exists?

Apparently, if the directory does not exist, then this is the expected error message (may be a typo?) as far as I can tell from the following lines:

github.com

rstudio/rmarkdown/blob/7ad693e10a7444de60e4f58bc3eef14eab212d35/R/render.R#L481


  if (!inherits(output_file, "AsIs") && xfun::file_ext(output_file) == "")
    output_file <- paste(output_file, xfun::file_ext(output_auto), sep = ".")
}


# if an output_dir was specified then concatenate it with the output file
if (!is.null(output_dir)) {
  output_file <- file.path(output_dir, basename(output_file))
}
output_dir <- dirname(output_file)


# Stop the render process early if the output directory does not exist
if (!dir_exists(output_dir)) {
  stop("The directory '", output_dir, "') does not not exist.",
       call. = FALSE)
}


# use output filename based files dir
files_dir_slash <- file.path(output_dir, knitr_files_dir(basename(output_file)))
files_dir <- pandoc_path_arg(files_dir_slash)


# default to no cache_dir (may be generated by the knit)
