Examples

# Convert a quarterly "ts"
ts1 <- ts(1:10, frequency = 4, start = c(1959, 2))
as.uts(ts1)

# Convert a monthly "ts"
ts2 <- ts(1:10, frequency = 12, start = c(1959, 8))
as.uts(ts2)

# Convert a yearly 'ts"
ts3 <- ts(1:10, frequency = 1, start = 1959)
as.uts(ts3)

# Convert an "fts"
if (requireNamespace("fts", quietly = TRUE)) {
  fts1 <- fts::fts(index=as.POSIXct("2016-01-01") + dhours(c(1, 4, 27)), data=c(5,4,7))
  as.uts(fts1)
}

# Convert an "irts"
if (requireNamespace("tseries", quietly = TRUE)) {
  irts1 <- tseries::irts(as.POSIXct("2015-01-01") + days(c(1, 3, 7, 9)), 1:4)
  as.uts(irts1)
}

# Convert an "xts"
if (requireNamespace("xts", quietly = TRUE)) {
  xts1 <- xts::xts(1:4, as.Date("2015-01-01") + c(1, 3, 7, 9))
  as.uts(xts1)
}

# Convert a "zoo"
if (requireNamespace("zoo", quietly = TRUE)) {
  zoo1 <- zoo::zoo(1:4, as.Date("2015-01-01") + c(1, 3, 7, 9))
  as.uts(zoo1)
