Get Column Names from a Time Series Lists
Usage
tsl_colnames_get(tsl = NULL, names = c("all", "shared", "exclusive"))Arguments
- tsl
(required, list) Time series list. Default: NULL
- names
(optional, character string) Three different sets of column names can be requested:
"all" (default): list with the column names in each zoo object in
tsl. Unnamed columns are tagged with the string "unnamed"."shared": character vector with the shared column names in at least two zoo objects in
tsl."exclusive": list with names of exclusive columns (if any) in each zoo object in
tsl.
