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")

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.
