R2GUESS-package Sparse Bayesian variable selection method for linear regression based analysis of possibly multivariate outcomes.
Analysis.permutation Computing the FDR-controlled level for the significance of the MPPI
as.ESS.object Compiles the main input and output files from a previous run of 'R2GUESS' and creates an ESS object.
boxplotbeta Draws boxplots of the posterior distribution of regression coefficient(s) for a given predictor
check.convergence Diagnostic plots for the evaluation of the convergence of the algorithm
data.X Data set compiling genotype data for 29 rats.
data.Y.Hopx Data set compiling gene expression levels (HOPX gene) for 29 rats.
example.as.ESS.object Function creating an 'ESS' object from the example files contained in the package
Extend.R2GUESS Extends an already finished 'R2GUESS' run for an extra user-defined number of iterations
FDR.permutation Performs parallel permuted runs of 'R2GUESS' and returns the empirical FDR-controlled level for the significance of the MPPI
get.g.sweep Internal function used to generate the regression coefficients. This function extracts the values of the shrinkage factor g for a given model specified by its ranked posterior probability
get.sweep.best.model Internal function used to generate the regression coefficients. This function extracts the sweep(s) for which each selected models has been visited along the MCMC run.
MAP.file MAP file describing genotypes from the rats experiment.
pairwise.correlation Calculates and plots the pairwise correlation between outcomes
plot.ESS Provides diagnostic plots to assess the convergence of the MCMC procedure along the run
plotcim Clustered Image Maps (CIMs) (heat maps)
plotcim.explore Plots a cluster image mapping of correlations between outcomes and all predictors
plotmodel Visualisation of the proximity between best models
plotMPPI Plots the marginal posterior probability of inclusion (MPPI) for each predictor
plotvariable Visualisation of the best models
Postprocess.R2GUESS Performs posterior inference from an interrupted 'R2GUESS' run.
print.ESS Provides a 'print' method for class 'ESS'
R2GUESS Wrapper function that reads the input files and parameter values required by GUESS, runs the C++ code from R and stores the main GUESS output in an 'ESS' object
Resume.R2GUESS Function resuming an interrupted 'R2GUESS' run
sample.beta Posterior distribution of the regression coefficients for a chosen model
summary.ESS 'summary' method for class 'ESS'
