Source: R/annotation_table_class.R
lcms_table.Rd

An annotation_table is an annotation_source() where the imported data.frame contains measured experimental data. An id_column of values is required to uniquely indentify each record (row) in the table (NB these are NOT molecule identifiers, which may be be present in multiple records).

Usage

lcms_table(
  data = data.frame(id = numeric(0), mz = numeric(0), rt = numeric(0)),
  tag = "",
  id_column = "id",
  mz_column = "mz",
  rt_column = "rt",
  ...
)

Arguments

data

(data.frame) A data.frame of annotation data. The default is data.frame(id = character(0)).

tag

(character) A (short) character string that is used to represent this source e.g. in column names or source columns when used in a workflow. The default is "".

id_column

(character) The column name of the annotation data.frame containing row identifers. If NULL This will be generated automatically. The default is "id".

...

Additional slots and values passed to struct_class.

Value
