I'm glad it's helpful! Defining it and then invoking it in ~/.Rprofile would work, but then you will need to be careful about managing both ./.Rprofile and ~/.Rprofile files. If you have one of the former, then the latter does not get sourced at startup (see ?Startup). Of course, you can put source('~/.Rprofile') in a local ./.Rprofile to take care of that if you want.
But in the long run, it would be a better practice to put personal helper functions like this in a package and then load it in your .Rprofile file(s). Most of my ./.Rprofile files have require(rmacq) setwid() in them (along with whatever other directory-specific startup actions I want). The more personal helper functions you have, the more valuable it will be to put them in a package instead of defining them in ~/.Rprofile. -Don -- Don MacQueen Lawrence Livermore National Laboratory 7000 East Ave., L-627 Livermore, CA 94550 925-423-1062 On 4/17/15, 4:36 PM, "Paul Domaskis" <paul.domas...@gmail.com> wrote: >Yes, I found the width option in the help pages, but I was wondering >if there was automatic setting of the wrapping according to the >current window width. > >Your function works exactly as I wished.
