correlation_matrix column selection
The correlation_matrix
function computes the correlation coefficients for either .obs
or .var
columns for the dimensions of an embedding. The columns
parameter can be used to select a list of columns for which the correlation will be computed. However, the current default is to select all numeric columns for computation. This may lead to undesired effects e.g. a clustering column could be numeric, which would skew the results. We should think about changing the default or a way to make sure to include only columns where it makes sense to compute a correlation.
