R6 class definition

Value

data frame

integer vector of valid electrodes

The same as value

A named list of key-value pairs, or if one key is specified and simplify=TRUE, then only the value will be returned.

A data frame with four columns: 'namespace' for the group name of the entry (entries within the same namespace usually share same module), 'timestamp' for when the entry was registered. 'entry_name' is the name of the entry. If include_history is true, then multiple entries with the same 'entry_name' might appear since the obsolete entries are included. 'entry_value' is the value of the corresponding entry.

If as_table is FALSE, then returns as RAVEEpoch instance; otherwise returns epoch table; will raise errors when file is missing or the epoch is invalid.

If simplify is true, returns a vector of reference electrode names, otherwise returns the whole table; will raise errors when file is missing or the reference is invalid.

If simplify is true, returns a vector of electrodes that are valid (or won't be excluded) under given reference; otherwise returns a table. If subset is true, then the table will be subset and only rows with electrodes to be loaded will be kept.

If simplify is true, returns a vector of frequencies; otherwise returns a table.

A table of pipeline registry
