Extract Shared Variation in Collections of Data Sets Using Regression Models

The algorithm extracts shared variation from a collection of data sets using regression models.

cocoreg is an R-package for extracting shared variation in collections of datasets using regression models.

A minimal usage example:

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)
