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.
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)
