Read 'Allotrope Simple Model' (ASM) 2D chromatograms

Reads 'Allotrope Simple Model' files into R.

Usage

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

Arguments

path

Path to ASM .json file.

data_format

Whether to return data in wide or long format.

format_out

Matrix or data.frame.

read_metadata

Logical. Whether to attach metadata.

metadata_format

Format to output metadata. Either chromconverter or raw.

collapse

Logical. Whether to collapse lists that only contain a single element. Defaults to TRUE.

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.
