Returns the n nearest words to a given word or sentence/document

1 |

`x` |
a character vector of |

`n` |
the number of neighbors to be computed |

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

`breakdown` |
if |

The format of `x`

should be of the kind `x <- "word1 word2 word3"`

instead of

`x <- c("word1", "word2", "word3")`

if sentences/documents are used as input. This allows for simple copy&paste-inserting of text.

To import a document *Document.txt* to from a directory for comparisons, set your working
directory to this directory using `setwd()`

. Then use the following command lines:

`fileName1 <- "Alice_in_Wonderland.txt"`

`x <- readChar(fileName1, file.info(fileName1)$size)`

.

Since `x`

can also be chosen to be any vector of the active LSA Space, this function can be
combined with `compose()`

to compute neighbors of complex expressions (see examples)

A named numeric vector. The neighbors are given as names of the vector, and their respective cosines to the input as vector entries.
