mean_razao: Ratio Root-Shoot Length

In SeedCalc: Seed Germination and Seedling Growth Indexes

Description

It calculates the Mean Ration Root-Shoot Length

Usage

mean_razao(lengths)

Arguments

lengths

A data.frame object containing seedling lengths data with four columns. The first and second columns are for identification, e.g. treatments and repetitions. The third is the shoot length and the fourth is the root length.

Examples

Seedling <- data.frame(
LOTE = c(1, 1, 1, 1, 1, 1, 1, 2, 2, 2, 2, 2, 2, 2, 2),
REP = c(1, 1, 1, 1, 2, 2, 2, 1, 1, 1, 1, 2, 2, 2, 2),
SH = c(0.00, 2.77, 1.18, 1.07, 0.80, 2.65, 3.51, 0.64, 2.77, 1.18, 1.07, 0.80, 2.65, 3.51, 1.98),
ROOT = c(4.86, 6.71, 7.88, 3.68, 9.68, 8.88, 9.85, 4.86, 6.71, 7.88, 3.68, 9.68, 8.88, 9.85, 8.75)
)
print(Seedling)
RSL <- mean_razao(Seedling)
