Subset Time Series Lists by Time Series Names, Time, and/or Column Names

Subset Time Series Lists by Time Series Names, Time, and/or Column Names

Usage

tsl_subset(
  tsl = NULL,
  names = NULL,
  colnames = NULL,
  time = NULL,
  numeric_cols = TRUE,
  shared_cols = TRUE
)

Arguments

tsl

(required, list) Time series list. Default: NULL

names

(optional, character or numeric vector) Character vector of names or numeric vector with list indices. If NULL, all time series are kept. Default: NULL

colnames

(optional, character vector) Column names of the zoo objects in tsl. If NULL, all columns are returned. Default: NULL

time

(optional, numeric vector) time vector of length two used to subset rows by time. If NULL, all rows in tsl are preserved. Default: NULL

numeric_cols

(optional, logical) If TRUE, only the numeric columns of the zoo objects are returned. Default: TRUE

shared_cols

(optional, logical) If TRUE, only columns shared across all zoo objects are returned. Default: TRUE

Value

time series list
