chromConverter (version 0.7.5)

read_agilent_d: Read files from 'Agilent ChemStation' .D directories

Description

Reads files from 'Agilent' .D directories.

Usage

read_agilent_d(
  path,
  what = c("chroms", "dad", "peak_table"),
  format_out = c("matrix", "data.frame", "data.table"),
  data_format = c("wide", "long"),
  read_metadata = TRUE,
  metadata_format = c("chromconverter", "raw"),
  collapse = TRUE
)

Value

A list of chromatograms in the format specified by data_format and #' format_out. If data_format is wide, the chromatograms will be returned with retention times as rows and columns containing signal intensity for each signal. If long

format is requested, retention times will be in the first column. The format_out argument determines whether the chromatogram is returned as a matrix, data.frame or data.table. Metadata can be attached to the chromatogram as attributes if read_metadata is TRUE.

Arguments

path

Path to 'Agilent' .D directory.
