chromConverter (version 0.7.5)

call_rainbow: Call 'rainbow' parsers Parse 'Agilent' or 'Waters' files with rainbow parsers

Description

Uses rainbow parsers to read in Agilent (.D) and Waters (.raw) files. If format_in is "agilent_d" or "waters_raw", a directory of the appropriate format (.d or .raw) should be provided to the file argument. If format_in is "chemstation_uv" a .uv file should be provided. Data can be filtered by detector type using the what argument.

Usage

call_rainbow(
  path,
  format_in = c("agilent_d", "waters_raw", "masshunter", "chemstation", "chemstation_uv",
    "chemstation_fid"),
  format_out = c("matrix", "data.frame", "data.table"),
  data_format = c("wide", "long"),
  by = c("detector", "name"),
  what = NULL,
  read_metadata = TRUE,
  metadata_format = c("chromconverter", "raw"),
  collapse = TRUE,
  precision = 1
)

Value

Returns a (nested) list of matrices or data.frames according to the value of format_out. Data is ordered according to the value of by.
