# pwr.omegasq

##### Power calculations for Omega Squared.

This function uses `pwr.anova.test`

from the `pwr`

package in combination with `convert.cohensf.to.omegasq`

and `convert.omegasq.to.cohensf`

to provide power analyses for Omega Squared.

- Keywords
- htest

##### Usage

```
pwr.omegasq(k = NULL, n = NULL, omegasq = NULL,
sig.level = 0.05, power = NULL, digits = 4)
```

##### Arguments

- k
The number of groups.

- n
The sample size.

- omegasq
The Omega Squared value.

- sig.level
The significance level (alpha).

- power
The power.

- digits
The number of digits desired in the output (4, the default, is quite high; but omega squared value tend to be quite low).

##### Details

This function was written to work similarly to the power functions in the `pwr`

package.

##### Value

An `power.htest.ufs`

object that contains a number of input and output values, most notably:

The (specified or computed) power

The (specified or computed) sample size in each group

The (specified or computed) significance level (alpha)

The (specified or computed) Omega Squared value

The computed value for the Cohen's *f* effect size measure

##### Examples

```
# NOT RUN {
pwr.omegasq(omegasq=.06, k=3, power=.8)
# }
```
