make_long {metan}

Two-way table to a 'long' format

Description

Helps users to easily convert a two-way table (genotype vs environment) to a 'long' format data. The data in mat will be gathered into three columns. The row names will compose the first column. The column names will compose the second column and the third column will contain the data that fills the two-way table.

Usage

make_long(mat, gen_in = "rows")

Arguments

mat

A two-way table. It must be a matrix or a data.frame with rownames.

gen_in

Where are the genotypes? Defaults to 'rows'. If genotypes are in columns and environments in rows, set to gen_in = 'cols'.

Value

A tibble with three columns: GEN (genotype), ENV (environment), and Y (response) variable.

Examples

library(metan)

set.seed(1)
mat <- matrix(rnorm(9, 2530, 350), ncol = 3)
colnames(mat) <- paste("E", 1:3, sep = "")
rownames(mat) <- paste("G", 1:3, sep = "")

make_long(mat)

gen_cols <- t(mat)
make_long(gen_cols, gen_in = "cols")
