unnest_tsibble(data, cols, key = NULL, validate = TRUE)A data frame contains homogenous tsibbles in the list-columns.
Names of columns to unnest.
Variable(s) that uniquely determine time indices. NULL for
empty key, and c() for multiple variables. It works with tidy selector
(e.g. dplyr::starts_with()).
TRUE suggests to verify that each key or each combination
of key variables leads to unique time indices (i.e. a valid tsibble). If you
are sure that it's a valid input, specify FALSE to skip the checks.
