smatr 3– an R package for estimation and inference about allometric lines

TLDR

We have content: Background: two sentences: "Summary 1." and "The Standardised Major Axis Tests and Routines (SMATR) software provides tools for estimation and inference about allometric lines, currently widely used in ecology and evolution." Purpose, Findings: "This paper describes some significant improvements to the functionality of the package, now available on R in smatr version 3." Mechanism: "New inclusions in the package include sma and ma functions that accept formula input and perform the key inference tasks; multiple comparisons; graphical methods for visualising data and checking (S)MA assumptions; robust (S)MA estimation and inference tools." Other: two lines: "2." and "3." These are just numbers? They might be placeholders. They are labeled Other. They contain no meaningful content. In that case compress metadata into a single very short sentence.

Abstract

Summary 1. The Standardised Major Axis Tests and Routines (SMATR) software provides tools for estimation and inference about allometric lines, currently widely used in ecology and evolution. 2. This paper describes some significant improvements to the functionality of the package, now available on R in smatr version 3. 3. New inclusions in the package include sma and ma functions that accept formula input and perform the key inference tasks; multiple comparisons; graphical methods for visualising data and checking (S)MA assumptions; robust (S)MA estimation and inference tools.
