Description Arguments Details Author(s) References Examples

An alternative to carrying out phenotypic adaptability and stability analysis, taking into account nonparametric statistics. Can be used as a robust approach, and less sensitive to departures from common genotypic, environmental, and GxE effects data assumptions (e.g., normal distribution of errors).

`function` |
nahu, kang, fox, or thsu |

`data` |
A numeric data.frame with fenotypic means values of MET, and genotypes and environments by rows and columns, respectively. |

`interaction` |
do a interaction plot or not (FALSE = no interaction plot output, TRUE = draws a interaction plot between genotypes and environments). |

The package can be applied to MET (multienvironment trials) data containing the phenotypic mean of genotype x environment (dataframe with genotypes by rows and environments into columns) and performs nonparametric analysis according to for criteria: H<c3><bc>hn (1979), and Nassar and H<c3><bc>hn (1987); Kang's (1988); Fox et al. (1990) and; Thennarasu's (1995).
