Target factory for csv features metadata import

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

Usage

import_fmetadata_csv_factory(files, col_ids, target_name_suffixes)

Arguments

files

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

col_ids

Character vector, the name of the column in each file that contains the features ID.

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:

• fmetadata_file_geno and fmetadata_file_transcripto: targets tracking the genomics and transcriptomics features metadata files, respectively.

• fmetadata_geno and fmetadata_transcripto: targets that import the genomics and transcriptomics features metadata dataset.

Examples

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

list(
  import_fmetadata_csv_factory(
    c(
      "data/genotype_fmetadata.csv",
      "data/rnaseq_fmetadata.csv"
    ),
    col_ids = c("Marker", "Info"),
    target_name_suffixes = c("geno", "transcripto")
  )
)
} # }
