Fuzzy Forests.
fuzzyforest
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
