Mean Germination Time
Description
This function calculates the mean germination time of germination according at the time lapse of the evaluations.
Usage
ger_MGT(evalName, data)
Arguments
evalName
Prefix of the names of the periods of evaluation.
data
The name of the data frame containing the data.
Details
It was proposed by Haberlandt in 1875. It is calculated as the weighted average germination time.
The number of germinated seeds at the intervals established for the collection of data is used as weight.
It is expressed in terms of the same units of time used in the germination count (CZABATOR, 1962).
Value
It returns an vector with the values of Mean Germination Time.

Examples
library(GerminaR)
dfr <- prosopis
mgt <- ger_MGT(evalName = "D", data = dfr)
