R Documentation

Read 'ChemStation' DAD files

Description

Agilent .uv files come in several different varieties. This parser can automatically detect and read several versions of these files from 'Agilent ChemStation' and 'Agilent OpenLab', including versions 31 and 131.

Usage

read_chemstation_uv(
  path,
  format_out = c("matrix", "data.frame", "data.table"),
  data_format = c("wide", "long"),
  read_metadata = TRUE,
  metadata_format = c("chromconverter", "raw"),
  scale = TRUE
)

Arguments

`path`	Path to `.uv` file.
`format_out`	Class of output. Either `matrix`, `data.frame`, or `data.table`.
`data_format`	Either `wide` (default) or `long`.
`read_metadata`	Logical. Whether to attach metadata.
`metadata_format`	Format to output metadata. Either `chromconverter` or `raw`.
`scale`	Whether to scale the data by the scaling factor present in the file. Defaults to `TRUE`.

Value

A 3D chromatogram in the format specified by data_format and format_out. If data_format is wide, the chromatogram will be returned with retention times as rows and wavelengths as columns. If long format is requested, three columns will be returned: one for the retention time, one for the wavelength and one for the intensity. The format_out argument determines whether the chromatogram is returned as a matrix or data.frame. Metadata can be attached to the chromatogram as attributes if read_metadata is TRUE.
