print.partition: Print methods for partition objects and equivalence objects

In RobinHankin/partitions: Additive Partitions of Integers

Print methods for partition objects and equivalence objects

Description

A print method for partition objects, summary partition objects, and equivalence classes. Includes various configurable options

Usage

## S3 method for class 'partition'
print(x, mat = getOption("matrixlike"), h = getOption("horiz"), ...)
## S3 method for class 'summary.partition'
print(x, ...)
## S3 method for class 'equivalence'
print(x, sep = getOption("separator"), ...)

Arguments

x	Object to be printed: an object of class either partition or summary.partition
mat	Boolean, with TRUE meaning to print like a matrix, and any other value meaning to print without column names (which usually results in more compact appearance)
h	Boolean governing the orientation of the printed matrix, with TRUE meaning to print with the rows being the partitions and any other value (the default) meaning to print the transpose
sep	Character vector, with special value of NULL interpreted as a comma; see examples section
...	Further arguments provided for compatibility

Details

The print method is sensitive to the value of option matrixlike which by default sets column names to a space for more compact printing. Set to TRUE to print a partition like a matrix. Option horiz specifies whether or not to print a partition horizontally.

Note

The print method for objects of class equivalence gives things like

listParts(3:1)
[[1]]
[1] {1,2,6}{4,5}{3}

[[2]]
[1] {1,2,6}{3,4}{5}

...

[[59]]
[1] {4,5,6}{1,2}{3}

[[60]]
[1] {4,5,6}{2,3}{1} 

The curly brackets are to remind you that function listParts() gives set partitions, not cycle representation of a permutation as per the permutations package.
