plot_contraction(x, prior_sd, parameters = NULL, scale = "sd", alpha = 0.8)

## Arguments

x |
object containing results (a data.frame or `SBC_results()` object). |

prior_sd |
a named vector of prior standard deviations for your parameters.
Either pass in analytically obtained values or use `calculate_prior_sd()` to get an empirical estimate from
an `SBC_datasets` object. |

parameters |
parameters to show in the plot or `NULL` to show all
must correspond a field already computed in the results (most likely `"mean"` and `"median"` ). |

scale |
which scale of variability you want to see - either `"sd"` for standard deviation
or `"var"` for variance. |

alpha |
the alpha for the points |

## Value

a ggplot2 plot object
