Momocs
News
- I’m still looking for funding to develop MomX. If you have any idea, please email me
<bonhomme.vincent@gmail.com>
- I’m available for consulting, training and collaboration, worldwide.
- Momocs is back on CRAN and no longer relies on the retired
rgeos
dependency - The tutorial/introduction is back! Download it there**
Installation
The last released version can be installed from CRAN with:
install.packages("Momocs")
But I recommend using (and only support) the development version from GitHub with:
# install.packages("devtools")
devtools::install_github("MomX/Momocs")
Example
This is a basic example of a complete analysis doing: inspection, normalization of raw outlines, elliptical Fourier transforms, dimmensionality reduction and classification, using a single line.
