Rmd files non chunks being read as comments

[yonicd]

Should the non chunk Rmd lines be read as comments?

I looked at this README.Rmd file and i get back this cloc output, which has a total of 83 lines.

cloc::cloc('README.Rmd')
      source language file_count file_count_pct loc loc_pct blank_lines blank_line_pct comment_lines comment_line_pct

here is the output with what clocks sees as comments removed

> cloc::cloc_remove_comments(source_file = normalizePath('README.Rmd'))
[1] "knitr::opts_chunk$set(\n  collapse = TRUE,\n  comment = \"#>\"\n)"

[hrbrmstr]

that's a gd q. i'd like to see others chime in. "comments" IMO are explaining code whereas text in Rmd may be just blathering so not sure it should be considered as comments.

[yonicd]

@maelle @ColinFay any strong opinions on the matter?

[maelle]

I do, I think they are not comments. I would not be horrified if in an analysis you simplified it this way, but wouldn't like cloc to do that. 🙂
