`chi2` |
Numeric, optional. If specified, a chi-squared distribution with |

`deg.f` |
Numeric. The degrees of freedom for the chi-squared distribution. Needs to be specified. |

`p` |
Numeric, optional. If specified, a chi-squared distribution with |

`xmax` |
Numeric, optional. Specifies the maximum x-axis-value. If not specified, the x-axis ranges to a value where a p-level of 0.00001 is reached. |

`geom.colors` |
user defined color for geoms. See 'Details' in |

`geom.alpha` |
Specifies the alpha-level of the shaded area. Default is 0.7, range between 0 to 1. |

# a simple chi-squared distribution
# for 6 degrees of freedom
dist_chisq(deg.f = 6)
# a chi-squared distribution for 6 degrees of freedom,
# and a shaded area starting at chi-squared value of ten.
# With a df of 6, a chi-squared value of 12.59 would be "significant",
# thus the shaded area from 10 to 12.58 is filled as "non-significant",
# while the area starting from chi-squared value 12.59 is filled as
# "significant"
dist_chisq(chi2 = 10, deg.f = 6)
# a chi-squared distribution for 6 degrees of freedom,
# and a shaded area starting at that chi-squared value, which has
# a p-level of about 0.125 (which equals a chi-squared value of about 10).
# With a df of 6, a chi-squared value of 12.59 would be "significant",
# thus the shaded area from 10 to 12.58 (p-level 0.125 to p-level 0.05)
# is filled as "non-significant", while the area starting from chi-squared
# value 12.59 (p-level < 0.05) is filled as "significant".
