[Rd] Treat multiline expressions as a single block in R Console history #1666

[Gabor Grothendieck]

Put this function in your .Rprofile file:

compress_clipboard <- function(sep = " ") {
  readLines("clipboard") |> paste(collapse = sep) |> writeClipboard()
}

and then run:

compress_clipboard()

before pasting.  Depending on what is on the clipboard you may need to
supply a different sep argument.
