fillData: Filling gaps for a dataset to balance

Description

fillData creates a balanced dataset in the long format to be used with the lmebreed solver for multi-trait models.

Usage

fillData(data, toBalanceSplit=NULL, toBalanceFill=NULL)

Value

$res

a data frame with traits in long format.

Arguments

data

a data frame with traits in wide format.

toBalanceSplit

variable to split the dataset for balancing.

toBalanceFill

variable of the factor to balance across the levels of the toBalanceSplit variable.
