propr (version 2.0.1)

propr: The propr Package

Description

Welcome to the propr package!

To learn more about how to calculate metrics of proportionality, see the help file for the functions phit and perb.

To learn more about the resultant propr class object, see the help file for the class definition propr-class.

To learn more about compositional data analysis, and its relevance to biological count data, see the bundled vignette.

To learn more about propr class methods, see below.

Usage

"show"(object)
"subset"(x, subset, select)
"["(x, i = "all", j)
"plot"(x, y, title = "Pairwise Proportionality")
"image"(x, cexRow = 10, cexCol = 10, title = "*LR Transformed Image")
dendrogram(object, title = "Proportional Clusters", group)

Arguments

object, x

An object of class propr.

subset

Subsets via object@counts[subset, ]. Use this argument to rearrange subject order.

select

Subsets via object@counts[, select]. Use this argument to rearrange feature order.

i

Operation used for the subset indexing. Select from "==", "=", ">", ">=", "

j

Reference used for the subset indexing. Provide a numeric value to which to compare the proportionality metrics.

y

Missing. Ignore. Leftover from the generic method definition.

title

A character string. A title for the propr plot.

cexRow

Numeric. Size of x-axis label.

cexCol

Numeric. Size of y-axis label.

group

A character or numeric vector. Supply feature groups for coloring. Feature groups expected in the order they appear in @counts.

Methods (by generic)
