Target factory for csv samples metadata import

Creates a list of targets that track each file and import the samples metadata from each csv file.

Usage

import_smetadata_csv_factory(files, col_ids, target_name_suffixes)

Arguments

files

Character vector, vector of paths to the samples metadata csv files.

col_ids

Character vector, the name of the column in each file that contains the ID of the rows (i.e. the sample IDs).

target_name_suffixes

Character vector, a suffix to add to the name of the targets created by this target factory for each dataset.

Value

A list of target objects. For example, with two files to import and target_name_suffixes = c("geno", "transcripto"), the factory returns the following targets:

• smetadata_file_geno and smetadata_file_transcripto: targets tracking the genomics and transcriptomics samples metadata files, respectively.

• smetadata_geno and smetadata_transcripto: targets that import the genomics and transcriptomics samples metadata datasets, respectively.

Examples

if (FALSE) { # \dontrun{
## in the _targets.R
library(moiraine)

list(
  import_smetadata_csv_factory(
    c(
      "data/genotype_smetadata.csv",
      "data/rnaseq_smetadata.csv"
    ),
    col_ids = c("Sample", "SampleIDs"),
    target_name_suffixes = c("geno", "transcripto")
  )
)
} # }
