# 2D- or 3D-Plot of a list of words

### Description

2D or 3D-Plot of mutual word similarities to a given list of words

### Usage

1 2 3 |

### Arguments

`x` |
a character vector of |

`dims` |
the dimensionality of the plot; set either |

`method` |
the method to be applied; either a Principal Component Analysis ( |

`connect.lines` |
(3d plot only) the number of closest associate words each word is connected with via line. Setting |

`axes` |
(3d plot only) whether axes shall be included in the plot |

`box` |
(3d plot only) whether a box shall be drawn around the plot |

`cex` |
(2d Plot only) A numerical value giving the amount by which plotting text should be magnified relative to the default. |

`tvectors` |
the semantic space in which the computation is to be done (a numeric matrix where every row is a word vector) |

`breakdown` |
if |

`alpha` |
(3d plot only) a vector of one or two numerics between 0 and 1 specifying the luminance of |

`col` |
(3d plot only) a vector of one or two characters specifying the color of |

`...` |
additional arguments which will be passed to |

### Details

Computes all pairwise similarities within a given list of words. On this similarity matrix, a Principal Component Analysis (PCA) or a Multidimensional Sclaing (MDS) is applied to get a two- or three-dimensional solution that best captures the similarity structure. This solution is then plottet.

For creating pretty plots showing the similarity structure within this list of words best, set `connect.lines="all"`

and `col="rainbow"`

### Value

see `plot3d`

: this function is called for the side effect of drawing the plot; a vector of object IDs is returned.

`plot_neighbors`

also gives the coordinate vectors of the words in the plot as a data frame
