method |
a character string to indicate if geometric (TRUE) or simple (FALSE) returns should be computed. |
na.rm |
a logical. Should missing values be removed? |
x |
a time series, may be an object of class "matrix",
or "timeSeries".
|
... |
arguments to be passed. |
all functions return an S4 object of class timeSeries.
## Simulated Monthly Return Data:
x = matrix(rnorm(24), ncol = 2)
