R: Combine calls to head and tail

headTail {psych} | R Documentation

## Combine calls to head and tail

### 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.

topBottom is just a call to headTail with ellipsis = FALSE and returning a matrix output.
