Description

A quick way to show the first and last n lines of a data.frame, matrix, or a text object. Just a pretty call to head and tail

Usage

headTail(x,hlength=4,tlength=4,digits=2,ellipsis=TRUE)
headtail(x,hlength=4,tlength=4,digits=2,ellipsis=TRUE)
topBottom(x,hlength=4,tlength=4,digits=2)

Arguments

x	A matrix or data frame or free text
hlength	The number of lines at the beginning to show
tlength	The number of lines at the end to show
digits	Round off the data to digits
ellipsis	Separate the head and tail with dots (ellipsis)

Value

The first hlength and last tlength lines of a matrix or data frame with an ellipsis in between. If the input is neither a matrix nor data frame, the output will be the first hlength and last tlength lines.
