copied!<p>For the purposes of teaching and preparing written instructions about R, one of the things that's always frustrated me is that I can't simply copy commands and output from R and paste them into another R session. For example, if I do something trivial, such as</p> <pre><code>> x <- rnorm(10) > x [1] 1.76975998 1.19722850 -0.39274507 -1.10979974 0.52320473 -0.08643833 [7] 0.94437690 0.08083207 0.62260363 1.89305469 </code></pre> <p>If I copy and paste that into a document or even here in this post, you (and my students) can not then just highlight it, copy it and paste it into an R session successfully</p> <pre><code>> > x <- rnorm(10) Error: syntax error > > x Error: syntax error > [1] 1.76975998 1.19722850 -0.39274507 -1.10979974 0.52320473 -0.08643833 Error: syntax error > [7] 0.94437690 0.08083207 0.62260363 1.89305469 Error: syntax error </code></pre> <p>You might want to do this to test your installation of R, compare my output to yours, or simply to make use of a function I've offered.</p> <p>So, what I'd like to be able to do is to change the default prompt from > to either an empty string or a blank space and also prefix all output lines with a hash mark #. That way, I could use R interactively to generate a session that looks like</p> <pre><code>x <- rnorm(10) x # [1] 1.76975998 1.19722850 -0.39274507 -1.10979974 0.52320473 -0.08643833 # [7] 0.94437690 0.08083207 0.62260363 1.89305469 </code></pre> <p>which <em>could</em> be copy/pasted into an R session successfully. It would make prepping R code for a journal article, students, lectures, etc. much easier for me (and maybe for others?)</p> <p>I've poked around the documentation with no luck... any ideas? pointers?</p> <p>Currently, I'm using R on a Mac either via the R.app GUI or from Terminal.</p>
