Germination.niche: Germination.niche

In micdimu/ecoseeds: Seed ecology - germination and morphometric analysis

Description

The function performs linear model with quadratic term to identify the value of the ideal environmental variable for germination (germination niche) from a series of tests. Indeed perform ANOVA and Tukey test. The results are plotted using boxplots, different letters indicate significant differences among tests. The figure is automatically saved in 16:9 at 300 dpi.

Usage

Germination.niche(germ_dyn, Nv.seed=NULL, n.seed=20,Env_Var=null)

Arguments

germ_dyn	germination dynamic matrix, row=tests, col=days, frist column=type of test
n.seed	number of seeds for each petri
Nv.seed	Number of not empty seeds, must be a vector or the column number where these values are located
Env.var	Environmental variable, the column number where these values are located

Value

M_env	Final germination percentage each petri with associated environmental varable
Z_env	Germination delay each petri with associated environmental varable
T50_env	T50 each petri with associated environmental varable
Plot_M_env	Smoothed fit for final germination percentage with boxplot for each test
Plot_Z_env	Smoothed fit for germination delay with boxplot for each test
Plot_T50_env	Smoothed fit for germination speed T50 with boxplot for each test
