one.sided {bspec} | R Documentation |

## Conversion between one- and two-sided spectra

### Description

Functions to convert between one- and two-sided
`bspec`

objects.

### Usage

```
one.sided(x, ...)
two.sided(x, ...)
## S3 method for class 'bspec'
one.sided(x, ...)
## S3 method for class 'bspec'
two.sided(x, ...)
```

### Arguments

`x` |
a |

`...` |
currently unused. |

### Details

The conversion only means that the `$two.sided`

element of the
returned `bspec`

object is set correspondingly, as internally always
the same (one-sided) spectrum is used.

### Value

A `bspec`

object
(see the help for the `bspec`

function).

### Examples

```
lhspec <- bspec(lh)
# compare distributions visually:
par(mfrow=c(2,1))
plot(lhspec)
plot(two.sided(lhspec))
par(mfrow=c(1,1))
# ...and numerically:
print(cbind("frequency"=lhspec$freq,
"median-1sided"=quantile(lhspec,0.5),
"median-2sided"=quantile(two.sided(lhspec),0.5)))
```
