ts_ turns an existing function into a function that can deal with
ts-boxable time series objects.
load_suggested(pkg) ts_(fun, class = "ts", vectorize = FALSE, reclass = TRUE) ts_apply(x, fun, ...)
Arguments
| pkg | external package, to be suggested (automatically added by |
|---|---|
| fun | function, to be made available to all time series classes |
| class | class that the function uses as its first argument |
| vectorize | should the function be vectorized? (not yet implemented) |
| reclass | logical, should the new function return the same same ts-boxable output as imputed? |
| x | ts-boxable time series, an object of class |
| ... | arguments passed to subfunction |
Value
A function that accepts ts-boxable time series as an input.
Details
The ts_ function is a constructor function for tsbox time series functions.
It can be used to wrap any function that works with time series. The default
is set to R base "ts" class. ts_ deals with the conversion stuff,
'vectorizes' the function so that it can be used with multiple time series.
