In r.jive: Perform JIVE Decomposition for Multi-Source Data

Description Details Author(s) References Examples

Performs the Joint and Individual Variation Explained (JIVE) decompositions on a list of data sets when the data share a dimension, returning low-rank matrices that capture the joint and individual structure of the data. It provides two methods of rank selection when the rank is unknown, a permutation test and a Bayesian Information Criterion (BIC) selection algorithm. Also included in the package are three plotting functions for visualizing the variance attributed to each data source: a bar plot that shows the percentages of the variability attributable to joint and individual structure, a heatmap that shows the structure of the variability, and principal component plots.

##Load data that were simulated as in Section 2.4 of Lock et al., 2013,
##with rank 1 joint structure, and rank 1 individual structure for each dataset
data(SimData) 
# Using default method ("perm")
Results <- jive(SimData)
summary(Results)

# Using BIC rank selection
BIC_result <- jive(SimData, method="bic")
summary(BIC_result)

###Load the permutation results
data(SimResults) 
# Visualize results
showVarExplained(Results)
# showVarExplained is also called by the "jive" S3 class default plot method

#show heatmaps
showHeatmaps(Results)

#show PCA plots
showPCA(Results,1,c(1,1))
