cocoreg
is an R-package for extracting shared variation in collections of datasets using regression models. The current stable release is available in CRAN:
http://cran.r-project.org/package=cocoreg
The algorithm is described in the paper:
Using regression makes extraction of shared variation in multiple datasets easy: Jussi Korpela, Andreas Henelius, Lauri Ahonen, Arto Klami, Kai Puolamäki, Data Mining and Knowledge Discovery, 2016. URL: http://dx.doi.org/10.1007/s10618-016-0465-y
The authors' version is available in this repository as cocoreg_plain.pdf. The final publication will be available at link.springer.com.
A minimal usage example:
library(cocoreg) dc <- create_syn_data_toy() ccr <- cocoreg(dc$data) shared.by.all.df <- variation_shared_by(dc, 'all') #only on synthetic datasets ggplot_dclst(list(observed = dc$data, shared = shared.by.all.df, cocoreg = ccr$data)) library(reshape) #importing from namespace does not work as expected ggcompare_dclst(list(shared = shared.by.all.df, cocoreg = ccr$data))
The most important functions in cocoreg are:
cocoreg()
which extracts shared variation from a collection of datasets
Functions to visualize output such as ggplot_dclst()
and ggcompare_dclst()
for lists of data collections, ggplot_dflst()
for lists of data.frames (i.e. one data collection) and ggplot_df()
for a single data.frame (a dataset)
Install the release version from CRAN:
install.packages("cocoreg")
Or the development version from GitHub:
# install.packages("devtools") # library(devtools) devtools::install_github("bwrc/cocoreg-r")
