knitr::opts_chunk$set(
  collapse = TRUE,
  comment = "#>"
)

library(erikmisc)

Read an Rmd file, update existing prefixed code chunks, and renumber. (These are replaced with a .txt extension to not interfere with other vignettes.)

e_rmd_name_chunks(
    fn_in             = "test_in_Rmd.txt"
  , fn_out            = "test_out_Rmd.txt"
  , prefix_chunk_name = "chunk-"
  )

Review the input and output files to see how the chunk header names have been updated.
