R Documentation

Display Numbers in Octal

Description

Convert or print integers in octal format, with as many digits as are needed to display the largest, using leading zeroes as necessary.

Usage

as.octmode(x)

## S3 method for class 'octmode':
as.character(x, ...)

## S3 method for class 'octmode':
format(x, ...)

## S3 method for class 'octmode':
print(x, ...)

Arguments

`x`	An object, for the methods inheriting from class `"octmode"`.
`...`	further arguments passed to or from other methods.

Details

Class "octmode" consists of integer vectors with that class attribute, used merely to ensure that they are printed in octal notation, specifically for Unix-like file permissions such as 755. Subsetting ([) works too.

as.octmode can convert integers (of type "integer" or "double") and character strings to class "octmode"

Examples

(on <- structure(c(16,32, 127:129),  class = "octmode")) #-> print.*()
##-> "020" "040" "177" "200" "201"
unclass(on[3:4]) # subsetting
