CoCo4R is an extension module that makes the CoCoNAD implementation available as a function in R and also includes functions for generating a pattern spectrum with the help of surrogate data and CoCoNAD analysis, for estimating a pattern spectrum and for pattern set reduction.
This extension module was developed for R 3.6.3 and has been tested up to now only on Linux Minit 20. However, there is no reason why it should not work on Microsoft Windows as well, since no Linux-specific functions have been used.
How to use the different functions can be seen in the test
coco4r_test.R made available above (which is
also available in the source package). Package documentation
is currently a bit sparse, but what is available can be accessed
help(coco4r) in R, after loading this extension
To install this extension library, unpack the sources to a new
directory and call
R CMD INSTALL coco4r in this directory.
Note that you may need root or administrator rights for the
installation, as R may want to copy some files to its system
More information about the CoCoNAD algorithm can be found in the following papers:
The use of pattern spectra to evaluate the statistical significance of found frequent item sets is explained in these papers (although for standard frequent item set mining, but the idea can be transferred, with a few adaptations, to CoCoNAD):
