Constructs a ts object from a tis
object. The tis object's starting year, starting
cycle, and frequency, along with the object's data, in a
call to the ts function.
# S3 method for tis
as.ts(x, ...)a tis object to be converted
Ignored
A ts object with the same data as x, and with
starting time and frequency given by:
start = c(year(xstart), cycle(xstart)) frequency = frequency(x)
The tis class covers more frequencies than the ts
class does, so the conversion may not be accurate.
