Thanks your reply. I totally agree with your option. But it is good to have this feature, since people are lazy, like me. Apparently I put a explicit prefix "##' " under the ess-mode-hook to avoid that. (setq adaptive-fill-first-line-regexp "##' " adaptive-fill-regexp "##' ") This works well but I am not good at regular expressions. So this workaround could not determine the prefix like "##'" plus some indents. Maybe people here can help me with this:). There is another issue that C-c C-o has destroyed my indents inside the comments. I would love to have an option to only update the parameters but keep the current indents. Hope this can be fixed in the new release:) Feng On Sat, Sep 11, 2010 at 12:54 AM, Henning Redestig < henning.red@googlemail.com> wrote: > 2010/9/11 Feng Li : > > I started to use Roxygen to document my R code and everything is perfect. > I > > turned auto-fill-mode on under the ess-mode-hook.
