The "digits" parameter is handled differently in your two cases: > format(c(49.85, 70632), digits=4) [1] " 49.85" "70632.00" > signif(c(49.85, 70632), digits=4) [1] 49.85 70630.00 Duncan Murdoch
Ah, thank you! (A bit strange.) Now looking more closer to it, I wonder whether I could achieve the following output formatting:> fivenum(E$nodes,1)[1] 1 2 3 7 70632> round(mean(E$nodes),2)[1] 49.85 That's a reasonable way of showing the numbers involved, since E$nodes is declared as integer data. Now could I get "summary" to show me the numbers in this way, i.e. Min. 1st Qu. Median Mean 3rd Qu. Max. 1 2 3 49.85 7 70630 ?? I guess not. Perhaps it would be helpful to see how "summary" achieves its result here --- how to display the code of this function? (Spent some time with the documentation and on the Internet, but can't find the right combination of key words, and a nice section "List everything related to functions" doesn't seem to be available.) Thanks for your help.
