fuzzyforest is an extension of random forests designed to yield less biased
variable importance rankings when features are correlated with one another.
The algorithm requires that features be partitioned into seperate groups
or modules such that the correlation within groups are large and the
correlation between groups is small. fuzzyforest allows for easy integration
the package WGCNA.
- the latest released version can be downloaded from CRAN:
install.packages("fuzzyforest")
To enable use of the full functionality of fuzzyforest packages WGCNA
must be installed. However, WGCNA requires the installation of a few
packages form bioConductor. To install WGCNA, type the following lines
into the console:
setRepositories(ind=1:2)
install.packages("WGCNA")
source("http://bioconductor.org/biocLite.R")
biocLite("AnnotationDbi", type="source")
biocLite("GO.db")
If further issues with the installation of WGCNA arise see the WGCNA
website: http://labs.genetics.ucla.edu/horvath/CoexpressionNetwork/Rpackages/WGCNA/index.html#manualInstall
