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().
