Fast clustering by automatic search and find of density peaks

ClusterX

This package implement the clustering algorithm described by Alex Rodriguez and Alessandro Laio (2014) [1] with improvements of automatic peak detection and parallel computing.

Installation

To install the latest version from the github repository, use:

if(!require(devtools)){
  install.packages("devtools") # If not already installed
}
devtools::install_github("JinmiaoChenLab/ClusterX")

Usage

After installing the package, use the following code to run a simple example (to install, see below).

dir <- system.file("extdata", package = "ClusterX")
r15 <- read.table(paste(dir, "R15.txt", sep = .Platform$file.sep), header = FALSE)
r15_c <- ClusterX(r15[,c(1,2)])
clusterPlot(r15_c)
peakPlot(r15_c)

d31 <- read.table(paste(dir, "D31.txt", sep = .Platform$file.sep), header = FALSE)
d31_c <- ClusterX(d31[,c(1,2)])
clusterPlot(d31_c)
densityPlot(d31_c)
peakPlot(d31_c)
