freq1way | R Documentation |

If hypothprob is absent: prints confidence intervals for the true proportions, a Chi-square test for uniformity, confidence intervals for differences in proportions (no corrections for multiple comparisons and plots the proportions.

```
freq1way(
counts,
hypothprob,
conf.level = 0.95,
addCIs = TRUE,
digits = 4,
arrowwid = 0.1,
estimated = 0
)
```

`counts` |
A 1-way frequency table as produced by |

`hypothprob` |
If present, a set of probabilities to test the cell counts against. |

`conf.level` |
confidence level for the confidence interval, expressed as a decimal. |

`addCIs` |
If true, adds confidence limits to plot of sample proportions. |

`digits` |
used to control rounding of printout. |

`arrowwid` |
controls width of arrowheads. |

`estimated` |
default is |

If hypothprob is present: prints confidence intervals for the true proportions, a Chi-square test for the hypothesized probabilities, and plots the sample proportions (with atached confidence limits) alongside the corresponding hypothesized probabilities. )

An invisible list containing the following components:

`CIs` |
a matrix containing the confidence intervals. |

`exp` |
a vector of the expected counts. |

`chi` |
a vector of the components of Chi-square. |

These confidence intervals have been Bonferroni adjusted for multiple comparisons. This function has been deprecated and will be removed from future versions of the package
