view function

View First/Last/Random n Elements/Rows of an Object

View the first or last or random n elements or rows of an object. Components of lists will be subset using iterative calls to view.

view(obj, n=5, last=FALSE, random=FALSE, print.console=TRUE, ...)

Arguments

• obj: object -- an R object to view.

• n: numeric -- first (default)/last/random n elements/rows of obj to view.

• last: logical -- if TRUE, last n elements/rows of obj are displayed.

• random: logical -- if TRUE, n random elements/rows (without replacement) of obj are displayed.

• print.console: logical -- if TRUE, print the results to the console (default).

  The results are also returned invisibly should the user wish to assign the output to an object.

• ...: dots -- additional arguments (e.g., replace=TRUE if specifying random=TRUE).

Returns

Invisibly returns the results of the call to view.

Note

If random=TRUE, random sampling will take place before the last operator is applied.
