compositions (version 2.0-2)

print.acomp: Printing compositional data.

Description

Prints compositional objects with appropriate missing encodings.

Usage

# S3 method for acomp
print(x,...,replace0=TRUE)
# S3 method for aplus
print(x,...,replace0=TRUE)
# S3 method for rcomp
print(x,...,replace0=FALSE)
# S3 method for rplus
print(x,...,replace0=FALSE)

Arguments

x

a compositional object

…

further arguments to print.default

replace0

logical: Shall 0 be treated as "Below detection Limit" with unkown limit.

Value

An invisible version of x.

Missing Policy

The policy of treatment of zeroes, missing values and values below detecion limit is explained in depth in compositions.missings.

Details

Missings are displayed with an appropriate encoding:

• MARMissing at random: The value is missing independently of its true value.

• MNARMissing NOT at random: The value is missing dependently of its true value, but without a known systematic. Maybe a better name would be: Value dependen missingness.

• BDLbelow detection limit (with unspecified detection limit): The value is missing because it was below an unkown detection limit.

• <Detectionlimitbelow detection limit (with specified detection limit): The value is below the displayed detection limit.

• SZStructural Zero: A true value is either bound to be zero or does not exist for structural nonrandom reasons. E.g. the portion of pregnant girls at a boys school.

• ERRError: An illegal encoding value was found in the object.
