Description Usage Arguments Examples

Plots a grid of contour plots. Each contour plot is a contour over two dimensions with the remaining two dimensions set to a value. See cf_highdim for functions with more than 4 dimensions.

``` |

`func` |
A four-dimensional function to plot contours of |

`over` |
Indices of the dimensions used for the outer grid |

`nover` |
Number of grid points for the outer grid dimensions |

`nover1` |
Number of grid points for the first outer grid dimension |

`nover2` |
Number of grid points for the second outer grid dimension |

`low` |
Low input value for each dimension |

`high` |
High input value for each dimension |

`same_scale` |
Should all contour plots be on the same scale? Takes longer since it has to precalculate range of outputs. |

`n` |
Number of points in grid on each dimension |

`batchmax` |
number of datapoints that can be computed at a time |

`var_names` |
Variable names to add to plot |

`pts` |
Matrix of points to show on plot |

`axes` |
axes |

`key.axes` |
key for bar plot |

`key.title` |
statements which add titles for the plot key. |

`nlevels` |
Number of levels in contour scale |

`color.palette` |
Color palette used for contour plots |

`edge_width` |
How wide should edges with variable names be? As proportion of screen section to left of bar. Either single value for both edges, or length two vector. |

`cex.var_names` |
Size of var_names printed on edges. |

`bar` |
Should a bar be added on right when all on same_scale? |

`bar_width` |
How wide should bar section of plot be? |

`over_srt` |
Degrees of rotation for the axis labels. Vector of length two. |

`...` |
Arguments passed to cf_func, and then probably through to cf_grid |

cf_4dim(
function(x) {x[1] + x[2]^2 + sin(2*pi*x[3])}
)
cf_4dim(function(x) x[1]*x[3] + sin(x[2]*x[4]), color.palette=heat.colors,
nover1=3, nover2=8, cex.var_names = .5)
cf_4dim(function(x) x[1]*x[3] + sin(x[2]*x[4]), color.palette=topo.colors,
nover1=3, nover2=8, cex.var_names = 1, over_srt = c(90,0),
edge_width=c(.1, .2), nlevels = 5)
