Construct a multiOmicDataSet object from tsv files.

Usage

create_multiOmicDataSet_from_files(
  sample_meta_filepath,
  feature_counts_filepath,
  count_type = "raw",
  sample_id_colname = NULL,
  feature_id_colname = NULL
)

Arguments

sample_meta_filepath: path to tsv file with sample IDs and metadata for differential analysis.
feature_counts_filepath: path to tsv file of expected feature counts (e.g. gene counts from RSEM).
count_type: type to assign the values of counts_dat to in the counts slot
sample_id_colname: name of the column in sample_metadata that contains the sample IDs. (Default: NULL - first column in the sample metadata will be used.)
feature_id_colname: name of the column in counts_dat that contains feature/gene IDs. (Default: NULL - first column in the count data will be used.)

Value

multiOmicDataSet object
