calc_lm2: Linear regression analysis of easynem-class (two-factor)

Description

The calc_lm2() function is used for linear regression analysis of easynem-class. Note: Both the horizontal and vertical coordinates of this function must be continuous variables.

Usage

calc_lm2(data, group1, group2, x, y, ...)

Value

Returns an lme2-class object storing the results of a linear regression analysis.

Arguments

data

An easynem-class object.

group1

x

X-axis.

y

Y-axis.

...

Other parameters of the lm function.

Details

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

nem_lm <- nem |> calc_lm2(con_crop, season, x = SOC, y = pH)
