## Data entry

The input can be in the form of wide format **raw data** or **summary statistics** where each row represents measurements of a single individual or population. In order to be recognized by the functions, columns need to have specific names (case sensitive):

**Sex** : either **M** for male or **F** for female (*Raw data*)
**Pop** : studied populations (*Summary/Raw data*)
**Trait** : studied traits or parameters (*Summary*)
**m** : male sample size (*Summary*)
**f** : female sample size (*Summary*)
**M.mu**: male mean (*Summary*)
**F.mu** : female mean (*Summary*)
**M.sdev** : male standard deviation (*Summary*)
**F.sdev** : female standard deviation (*Summary*)

**N.B**

- All non numerical values need to be factors.
- The list and the data frame formats for the
`multivariate`

and `raw_gen`

functions input, can be be found in the attached data sets under the names `baboon.parms_list`

and `baboon.parms_df`

respectively.
