Perform unnesting of signals

The `signal`-list column gets unnested. This function can be seen as the inversion of mbte_nest_signals.

mbte_unnest_signals(x)

Arguments

x	A tbl_mbte.

Value

A tbl_mbte with the following columns:

desc

`desc` is a placeholder for all the columns except the `fits`- column. Those columns can be seen as descriptive columns.

time

The time column (originally in the `signal`-column).

value

The signal-values (before in the `signal`-list-column).

Note

The `fits`-column will be removed, if it is present.

# create a tbl_mbte to nest
tbl <- raw_signals %>%
  group_by(mv) %>%
  new_tbl_mbte(time = "t", value = "value")

# nest signals and unnest them (should be equal to `tbl`)
nested <- mbte_nest_signals(tbl)
unnested <- mbte_unnest_signals(nested)

all.equal(unnested, tbl) # TRUE
