radial.meta | R Documentation |

Draw a radial plot (also called Galbraith plot) which can be used to assess bias in meta-analysis.

## S3 method for class 'meta' radial( x, xlim = NULL, ylim = NULL, xlab = "Inverse of standard error", ylab = "Standardised treatment effect (z-score)", common = TRUE, axes = TRUE, pch = 1, text = NULL, cex = 1, col = NULL, level = NULL, warn.deprecated = gs("warn.deprecated"), fixed, ... ) ## Default S3 method: radial( x, y, xlim = NULL, ylim = NULL, xlab = "Inverse of standard error", ylab = "Standardised treatment effect (z-score)", common = TRUE, axes = TRUE, pch = 1, text = NULL, cex = 1, col = NULL, level = NULL, ... )

`x` |
An object of class |

`xlim` |
The x limits (min, max) of the plot. |

`ylim` |
The y limits (min, max) of the plot. |

`xlab` |
A label for the x-axis. |

`ylab` |
A label for the y-axis. |

`common` |
A logical indicating whether the pooled common effect estimate should be plotted. |

`axes` |
A logical indicating whether axes should be drawn on the plot. |

`pch` |
The plotting symbol used for individual studies. |

`text` |
A character vector specifying the text to be used instead of plotting symbol. |

`cex` |
The magnification to be used for plotting symbol. |

`col` |
A vector with colour of plotting symbols. |

`level` |
The confidence level utilised in the plot. |

`warn.deprecated` |
A logical indicating whether warnings should be printed if deprecated arguments are used. |

`fixed` |
Deprecated argument (replaced by 'common'). |

`...` |
Graphical arguments as in |

`y` |
Standard error of estimated treatment effect. |

A radial plot (Galbraith 1988a,b), also called Galbraith plot, is
drawn in the active graphics window. If `common`

is TRUE, the
pooled estimate of the common effect model is plotted. If
`level`

is not NULL, the corresponding confidence limits are
drawn.
