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 |

arguments to be passed. |
all functions return an S4 object of class timeSeries
.
## Simulated Return Data -
x = matrix(rnorm(24), ncol = 2)
