Generic method for creating an eikosogram

```
eikos(y, x = NULL, data = NULL, marginalize = NULL, main = "",
main_size = 16, ylabs = TRUE, ylab_rot = 0, yname_size = 12,
yvals_size = 12, yaxs = TRUE, yprobs = NULL, yprobs_size = 8,
xlabs = TRUE, xlab_rot = 0, xname_size = 12, xvals_size = 12,
xaxs = TRUE, xprobs = NULL, xprobs_size = 8, vertical_xprobs = TRUE,
ispace = list(bottom = 8, left = 2, top = 2, right = 5), legend = FALSE,
col = NULL, bottomcol = "steelblue", topcol = "snow2", lcol = "black",
draw = TRUE, newpage = TRUE, lock_aspect = TRUE)
```

`y` |
Either the name of a variable in the data set (eikos.default), or a formula of such variables (eikos.formula). |

`x` |
name(s) of any conditional variable(s) (horizontal axis). Should be null if formula given. |

`data` |
data frame or table |

`marginalize` |
variable(s) to marginalize on, or NULL if none. Marginalized variables still appear in plot. |

`main` |
title of plot |

`main_size` |
font size of title (in points) |

`ylabs` |
logical, whether y labels should appear or not. |

`ylab_rot` |
rotation of y labels |

`yname_size` |
font size of vertical axis names (in points) |

`yvals_size` |
font size of labels for values of y variable (in points) |

`yaxs` |
logical, whether y axis should appear or not. |

`yprobs` |
probabilities to be shown on y-axis. NULL if they should be calculated from the data. |

`yprobs_size` |
font size of labels for horizontal probabilities (in points) |

`xlabs` |
logical, whether x labels should appear or not. |

`xlab_rot` |
rotation of x labels |

`xname_size` |
font size of horizontal axis names (in points) |

`xvals_size` |
font size of labels for values of x variables (in points) |

`xaxs` |
logical, whether x axis should appear or not. |

`xprobs` |
probabilities to be shown on x-axis. NULL if they should be calculated from the data. |

`xprobs_size` |
font size of labels for horizontal probabilities (in points) |

`vertical_xprobs` |
logical, whether probabilities on x axis should be rotated vertically. |

`ispace` |
list of four items (bottom, left, top, right) indicating the margins separating the text around the diagram. Each value is a positive integer giving a measure in "points". |

`legend` |
logical, whether to include legend |

`col` |
a vector of colours to match the response values. If NULL (the default), the colours are constructed as a smooth transition from 'bottomcol' to 'topcol' via 'grDevices::colorRampPalette |

`bottomcol` |
bottom colour |

`topcol` |
top colour |

`lcol` |
colour of lines |

`draw` |
logical, whether to draw eikosogram. |

`newpage` |
logical, whether to draw on a newpage. |

`lock_aspect` |
logical, whether to force entire plot to 1:1 aspect ratio. |

```
eikos("Hair", "Eye", data=HairEyeColor, legend = TRUE)
eikos(gear ~ cyl, data = mtcars)
eikos(Admit ~ Gender + Dept, data = UCBAdmissions,
yaxs = FALSE, xaxs = FALSE,
lock_aspect = FALSE,
xlab_rot = 90, xvals_size = 8,
ispace = list(bottom = 15))
```
