# TestDimorph

Analysis Of The Interpopulation Difference In Degree of Sexual Dimorphism Using Summary Statistics

## Installation

You can install the released version of TestDimorph from CRAN with:

`install.packages("TestDimorph")`

or the development version from GitHub:

`devtools::install_github("bassam-abulnoor/TestDimorph")`

## Acknowledgement

The authors would like to express their endless gratitude to **Prof. Konigsberg** for his contribution to this package with authentic code used in the `multivariate`

, `extract_sum`

,`RawGen`

functions, data sets used in the examples and for his overall valuable work in the field of physical anthropology without which this package wouldn’t have been possible.

## 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 a specific name (case sensitive):

**Sex** : Either **M** for male or **F** for female (*Raw data*)
**Pop** : Populations of the measured individuals (*Summary/Raw data*)
**Parms** : Measured numerical parameters for multivariate analysis and raw data generation (*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 entered as factors.
- The list and the data frame formats for the
`multivariate`

and `RawGen`

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

and `baboon.parms_df`

respectively.
- In the input of most of the functions, columns are referred to by number to avoid confusion.
