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")

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):

  1. Sex : either M for male or F for female (Raw data)
  2. Pop : studied populations (Summary/Raw data)
  3. Trait : studied traits or parameters (Summary)
  4. m : male sample size (Summary)
  5. f : female sample size (Summary)
  6. M.mu: male mean (Summary)
  7. F.mu : female mean (Summary)
  8. M.sdev : male standard deviation (Summary)
  9. F.sdev : female standard deviation (Summary)
