Details

Raw data is entered in a wide format data frame similar to Howells data set. The first two columns contain sex `Sex` (`M` for male and `F` for female) (Default: `1`) and populations' names `Pop` (Default:`2`). Starting from `firstX` column (Default: `3`), measured parameters are entered each in a separate column.

Examples

# for multivariate test
library(TestDimorph)
extract_sum(Howells, test = 4)
# for univariate test on a specific parameter
library(TestDimorph)
extract_sum(Howells, test = 2, firstX = 4)
