calculate median correlations — median_correlations • visualizationQualityControl

Given a correlation matrix and optionally the sample class information, calculates the median correlations of each sample to all other samples in the same class. May be useful for determining outliers.

Usage

median_correlations(cor_matrix, sample_classes = NULL, between_classes = FALSE)

Arguments

cor_matrix: the sample - sample correlations
sample_classes: the sample classes as a character or factor
between_classes: should the between class correlations be evaluated?

Value

data.frame

Details

The data.frame has 6 columns:

med_cor: the median correlation with other samples
sample_id: the sample id, either the rowname or an index
sample_class: the class of the sample. If not provided, set to "C1"
compare_class: the class of the other sample
plot_class: sample_class::compare_class for easy grouping
group: whether the median is within or between groups of samples
