Center and scale a `"timeSeries"`

object.

```
## S4 method for signature 'timeSeries'
scale(x, center = TRUE, scale = TRUE)
```

`x` |
an object from class |

`center` , `scale` |
a numeric vector or a logical value, see ‘Details’. |

`scale`

centers and/or scales the columns of a
`"timeSeries"`

object.

The value of `center`

determines how column centering is
performed. If `center`

is a numeric vector with length equal to
the number of columns of `x`

, then each column of `x`

has
the corresponding value from `center`

subtracted from it. If
`center`

is TRUE then centering is done by subtracting the column
means (omitting NAs) of `x`

from their corresponding columns, and
if `center`

is FALSE, no centering is done.

The value of `scale`

determines how column scaling is performed
(after centering). If `scale`

is a numeric vector with length
equal to the number of columns of `x`

, then each column of
`x`

is divided by the corresponding value from `scale`

. If
`scale`

is TRUE then scaling is done by dividing the (centered)
columns of `x`

by their standard deviations if `center`

is
TRUE, and the root mean square otherwise. If `scale`

is FALSE, no
scaling is done.

a centered and/or scaled `"timeSeries"`

object

```
## Load Series:
x <- 100* LPP2005REC[, c("SBI", "SPI")]
## Scale and Center -
X <- scale(x)
hist(X[, 1], prob=TRUE)
s <- seq(-3, 3, length=201)
lines(s, dnorm(s), col="red")
