Description

This function takes as input one object containing a test result and returns its most important informations. Function adonisText takes the result of a permutation test for a (returned from a call to the permutest function after betadisper, both from the vegan package), returning its F (with corresponding model and residuals degrees of freedom) and P-values for a selected variable in the result. In addition, it offers options to customize the output, changing separators and decimal markers (helpful in case you are producing a manuscript in German or Portuguese), and choosing the number of digits to round number to.

Usage

1
betadisperText(x, sep = "; ", dec = ".", digits = c(3, 3))

Arguments

x

Name of the object containing the result of the analysis from which stats should be extracted.

sep

How to separate pieces of information displayed. Defaults to a semicolon followed by a space (sep = "; ").

dec

Which decimal separator should be used? Defaults to ".". Allows to quickly changing to a comma in case you are producing a manuscript in German or Portuguese.

digits

How many digits should be kept for each piece of numeric information? Defaults to c(3, 3). Importantly, when a P-value rounded to the number of digits hereby defined results in zero, the result is replaced by a more theoretically meaningful alternative (e.g. P < 0.001).

Value

A string of text to be included in a markdown object.
