  subset = NULL,
  cores = NULL,
  output_dir = NULL,
  workspace_dir = "."
)

Arguments

input	Test data on which to perform variable selection operations. Must be CSV, rds, or feather.
operations	List of operations to perform, as strings. Supported operations: "correlation_threshold", "variance_threshold", "replicate_correlation". See cytominer::select.
replicates	Number of replicates to select per plate map. Required for the operation "replicate_correlation". See cytominer::preselect. default: NULL.
batch_id	Batch ID. Used for generating output_dir if the latter is not specified. default: NULL.
subset	Query to create the training data by subsetting. Regex must select CSVs only. Default selects everything. default: NULL.
cores	Optional integer specifying number of CPU cores used for parallel computing using doParallel. default: NULL.
