read_ml_datasets: Reads model files for running predictive models.

In jbryer/mldash: Evaluating Machine Learning Models Across Many Datasets

Reads model files for running predictive models.

Description

Information about models that can be used in the predictive models are stored in Debian Control Files (dcf). This is the similar to the format used in RMarkdown YAML (i.e. metadata).

Usage

read_ml_datasets(
  dir = c(paste0(find.package("mldash"), "/datasets")),
  cache_dir = dir,
  pattern = "*.dcf",
  use_cache = TRUE,
  check_for_missing_packages = interactive()
)

Arguments

dir	directory containing the dcf files for the datasets.
pattern	optional regular expression that is used when finding files to read in. It defaults to all dcf files in the dir, but could be a single filename to test a metadata file.
use_cache	whether to read data from the cache if available. If FALSE, then the data will be retrieved from the data function parameter.
check_for_missing_packages	if TRUE you will be prompted to install missing packages.
data_cache	directory where rds data files will be stored.
