Hello everybody,
I would like to announce that our new version of the Rfast R package has been released. We not only have dramatic speed improvements, but also have in some case the impossible to do with R made possible.
We use C++ and also take into advantage linear algebra or the mathematics behind to do our job. To give an example, variance components using MLE in a balanced design with 50,000 variables. This is in R (no C++ behind) and the result should be returned in at most 1 second (!!!). For this, we used the formula we found in Demidenko's book for mixed models.
If you want to be part of this project, have suggestions, ideas, corrections, spotted errors, or anything, please email Manos (the maintainer) or myself.
Have a nice day,
Michail
