This function is used to check the individual growth per group over time.

Usage

check_growth(data, yearly = FALSE)

Arguments

data: Dataframe with information about individual age based growth over time. This should be generated with preprocess(). You can test either structural or reserve weight.
yearly: Logical specifying if relative change in individual weight shall be calculated on a yearly basis (TRUE) ot not (FALSE). Default is FALSE.

Value

Dataframe showing the output of the linear model fit (slope & F-statistic) per group and age.
