Given a large data.frame, a function trains a series of models by looping over
two steps:
1. Create a model-specific subset of the complete training data
2. Train a model on the subset data
The function returns a list of trained models which are later used for
prediction on test data.
Due to h
I am developing R functions that interface with C++ code from the OpenCV
library. During development and unit testing, I embed an R instance to prepare
the environment in which the function encapsulating OpenCV code is called.
Running the unit testing suite results in starting (and later termin
I intend to submit a newly developed package to CRAN (to be licensed under the
GPL), which prompted me to re-read the GPL FAQ. The following section caught my
attention:

Dear Simon
Thank you for the link. This is exactly the kind of statement that I was
looking for.
I searched the archives for any mention of the GPL, for posts by Prof. Leisch
and some other keywords before posting to the list. Could this statement be
added to the R FAQ and/or the CRAN reposito

I am not trying to offer my own interpretation of the GPL, which is entirely
irrelevant. (If anyone is interested, I fall on the "pr
