view {NCStats}R Documentation

Shows a random selection of rows from a data frame.

Description

Shows, either to the console or to a pager, a random selection of rows from a data frame.

Usage

view(x,which=NULL,n=NULL,win=FALSE,title=NULL,row.names=TRUE)

Arguments

x A data frame.
which A numeric or string vector containing the column numbers or names to display. Defaults to showing all columns.
n A numeric indicating the number of rows to display. Defaults to 6 when win=FALSE and dim(x)[1] when win=TRUE.
win A logical indicating whether x should be displayed in a new window or not.
title A string for labeling the new window if win=TRUE. Defaults to the name of the x object.
row.names A logical indicating whether row names should be printed or not.

Value

No value is returned but a random (but sorted) selection of rows from the data frame is displayed.

Note

If n is larger than the number of rows in x or is non-numeric then x is displayed without randomizing the rows.
