print only a few lines of an object
Well, that depends whether the object has/inherits from a class for which there is a suitable method for head/tail and for printing the result. So I think your before-thought applies :-) Bert Gunter "The trouble with having an open mind is that people keep coming along and sticking things into it." -- Opus (aka Berkeley Breathed in his "Bloom County" comic strip ) On Wed, Mar 23, 2022 at 12:42 PM Jeff Newmiller

After-thought... Why not just use head() and tail() like normal R users do? On March 23, 2022 12:31:46 PM PDT, Jeff Newmiller <jdnewmil at dcn.davis.ca.us> wrote:
Sure. Re-define the print method for those objects. Can't say I recommend this, but it can be done. On March 23, 2022 11:44:01 AM PDT, Naresh Gurbuxani <naresh_gurbuxani at hotmail.com> wrote:
In an R session, when I type the name of an object, R prints the entire object (for example, a 20000 x 5 data.frame). Is it possible to change the default behavior so that only the first five and last five rows are printed? Similarly, if the object is a 20000 x 200 matrix, the default behavior will be to print first five and last five columns, combined with first five and last five rows. Thanks, Naresh
