Agilent .ch
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 30
and
130
, which are generally produced by ultraviolet detectors, as well as
81
, 179
, and 181
which are generally produced by flame
ionization (FID) detectors.
Arguments
- path
Path to
.ch
file- format_out
Matrix or data.frame.
- data_format
Whether to return data in
wide
orlong
format.- read_metadata
Logical. Whether to attach metadata.
- metadata_format
Format to output metadata. Either
chromconverter
orraw
.
Value
A 2D 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 a single column for the intensity.
If long
format is requested, two columns will be returned: one for the
retention time 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.
