R: Show some values from a vector

vectorShow {oce} | R Documentation

## Show some values from a vector

### Description

This is similar to `str()`, but it shows data at the first and last of the vector, which can be quite helpful in debugging.

### Usage

    vectorShow(v, msg, postscript, digits = 5, n = 2L)

### Arguments

`v` | the vector.
`msg` | optional character value indicating a message to show, introducing the vector. If not provided, then a message is created from `v`. If `msg` is a non-empty string, then that string is pasted together with a colon (unless `msg` already contains a colon), before pasting a summary of data values.
`postscript` | optional character value indicating an optional message to append at the end of the return value.
`digits` | for numerical values of `v`, this is the number of digits to use, in formatting the numbers with `format()`; otherwise, `digits` is ignored.
`n` | number of elements to show at start and end. If `n` is negative, then all the elements are shown.

### Value

A string ending in a newline character, suitable for display with `cat()` or `oceDebug()`.
