trans_formula: Formula conversion for easynem's meta

In easynem: Nematode Community Analysis

Formula conversion for easynem's meta

Description

The trans_formula() is used to convert the formula of easynem meta. Formula transformation is sometimes necessary in nematode community analysis. For example, to ensure that the data is normally distributed, it is often necessary to perform ln(x+1) transformation or other forms of formula transformation on nematode abundance. This function only works on a single variable. For a vectorized variant of this function, see trans_formula_v.

Usage

trans_formula(data, var, formu)

Arguments

data	An easynem-class data.
var	Variable name to be converted.
formu	Formula parameters for data conversion. Such as ~log(x+1).

Details

To facilitate code interpretation, it is recommended to use the pipe symbol |> to connect functions:

nem_trans <- nem |> trans_formula(Mesorhabditis, ~log(x+1))

Value

An easynem-class data that stores the result of formula conversion.
