split_sample: Split Sample

In scregclust: Reconstructing the Regulatory Programs of Target Genes in scRNA-Seq Data

Split Sample

Description

Splits sample in train and test set

Usage

split_sample(
  z,
  stratification,
  is_regulator,
  split_indices,
  split1_proportion,
  total_proportion,
  center
)

Arguments

z	matrix of single cell data with rows as genes and columns as cells.
stratification	a vector by which the sampling will be stratified of length ncol(z)
is_regulator	an indicator vector, telling which rows in z are candidate regulators
split_indices	a vector of given split indices. can be NULL
split1_proportion	proportion to include in first data split
total_proportion	proportion of data to include overall in splitting
center	TRUE if data should be row-centered. Set to FALSE otherwise.

Value

a list containing

z1_reg	first data split, TF-part
z2_reg	second data split, TF-part
z1_target	first data split, non-TF part
z2_target	second data split, non-TF part
split_indices	either verbatim the vector given as input or a vector encoding the splits as NA = not included, 1 = split 1 or 2 = split 2. Allows reproducibility of data splits.
