[help] tar_render() puts the result in a different directory when there is a space in the filename (or not)

Description

I think that I have found a bug in tar_render().

In the example below, tar_render() places the .pdf from "report 2.Rmd" in the current directory while it puts the .pdf from "report_1.Rmd" in the "report" directory. I had expected the results from both to be in the "report" directory.

library(targets)
tar_script({
library(targets)
library(tarchetypes)

dir.create("report", showWarnings = FALSE)
rmd_contents <- c("---", "title: \"Untitled\"", "output: pdf_document", "---", "", "# Something here")
writeLines(text = rmd_contents, con = "report/report_1.Rmd", sep = "\n")
writeLines(text = rmd_contents, con = "report/report 2.Rmd", sep = "\n")

list(
  tar_render(
    report1,
    "report/report_1.Rmd"
  ),
  tar_render(
    report2,
    "report/report 2.Rmd"
  )
)
})
tar_make()
#> ▶ start target report1
#> ● built target report1 [2.297 seconds]
#> ▶ start target report2
#> ● built target report2 [3.359 seconds]
#> ▶ end pipeline [5.781 seconds]

Indeed you may have found a bug, but it is not in tarchetypes because I can reproduce it with just rmarkdown.

tmp <- tempfile()
dir.create(tmp)
setwd(tmp)

dir.create("report", showWarnings = FALSE)
rmd_contents <- c("---", "title: \"Untitled\"", "output: pdf_document", "---", "", "# Something here")
writeLines(text = rmd_contents, con = "report/report_1.Rmd", sep = "\n")
writeLines(text = rmd_contents, con = "report/report 2.Rmd", sep = "\n")

library(rmarkdown)

report1 <- render("report/report_1.Rmd", knit_root_dir = ".")

Ah, thanks for that info. With that knowledge in hand, it appears to be a known issue rstudio/rmarkdown#2128
