R equivalent of bash's set -x; echo all commands being executed?
<p>In bash, if you enable <code>set -x</code>, the script will echo the evaluated form of all commands to the stderr logs. In tcsh, this same is accomplished with <code>set echo</code>. Is there something similar for R? It would help debugging if I had more verbose output of what the script commands look like as they are being run, without having to manually <code>print</code> or <code>cat</code> every single one. </p>
