generateTestData_1D: Generate simulated 1D dataset for testing

In evelinag/clusternomics: Integrative Clustering for Heterogeneous Biomedical Datasets

Description

Generate simple 1D dataset with two contexts, where the data are generated from Gaussian distributions. The generated output contains two datasets, where each dataset contains 4 global clusters, originating from two local clusters in each context.

Usage

generateTestData_1D(groupCounts, means)

Arguments

groupCounts	Number of data samples in each global cluster. It is assumed to be a vector of four elements: c(c11, c21, c12, c22) where cij is the number of samples coming from cluster i in context 1 and cluster j in context 2.
means	Means of the simulated clusters. It is assumed to be a vector of two elements: c(m1, m2) where m1 is the mean of the first cluster in both contexts, and m2 is the mean of the second cluster in both contexts.

Value

Returns the simulated datasets together with true assignmets.

data	List of datasets for each context. This can be used as an input for the contextCluster function.
groups	True cluster assignments that were used to generate the data.

Examples

groupCounts <- c(50, 10, 40, 60)
means <- c(-1.5,1.5)
testData <- generateTestData_1D(groupCounts, means)
# Use the dataset as an input for the contextCluster function for testing
datasets <- testData$data
