Prepare the data for weight training

Usage

prepare_data_for_training(
  path_to_gs,
  exprs,
  level = 1,
  scaled = FALSE,
  clusters = NULL
)

path_to_gs: Path to the gene set file without weights
exprs: The expression matrix, or a seurat object (rows: genes, columns: samples/cells)
level: The level of the gene sets to train weights for if you have multiple levels of gene sets.
scaled: Whether the expression matrix is scaled
clusters: The cell types of the cells. When exprs is a Seurat object, it can be NULL (default) to take the cell types from Seurat::Idents(), or a column name in the meta.data of the Seurat object that holds the cell type of each cell. When exprs is a matrix, it should be a named vector of cell types (names - cell names).
