[R] error with summary(vector)??

[Oliver Kullmann]

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.

Oliver
