Annotations will be matched to the measured variable meta data.frame by determining which annotations rt window overlaps with the rt window from the measured rt.

Usage

rt_match(variable_meta, rt_column, rt_window, id_column, ...)

Arguments

variable_meta

(data.frame) A data.frame of variable IDs and their corresponding rt values.

rt_column

(character) Column name of the rt values in variable_meta.

rt_window

(numeric, integer) Rt window to use for matching. If a single value is provided then the same rt is used for both variable meta and the annotations. A named vector can also be provided e.g. c("variable_meta"=5,"annotations"=2) to use different windows for each data table.

id_column

(character) Column name of the variable ids in variable_meta. id_column="rownames" will use the rownames as ids.

...

Additional slots and values passed to struct_class.

Value

A rt_match object with the following output slots:

updated(annotation_table) The input annotation source with the newly generated column.

Inheritance

A rt_match object inherits the following struct classes:

rt_match()model()struct_class()

Examples

M = rt_match(
      variable_meta = data.frame(id=NA),
      rt_column = character(0),
      rt_window = numeric(0),
      id_column = character(0))
#> Error in rt_match(variable_meta = data.frame(id = NA), rt_column = character(0),     rt_window = numeric(0), id_column = character(0)): If providing two retention time windows then the vector must be named e.g. c("variable_meta" = 5, "annotations"= 2)
