EmbedDimension | R Documentation |

`EmbedDimension`

uses `Simplex`

to evaluate
prediction accuracy as a function of embedding dimension.

```
EmbedDimension(pathIn = "./", dataFile = "", dataFrame = NULL, pathOut = "",
predictFile = "", lib = "", pred = "", maxE = 10, Tp = 1, tau = -1,
exclusionRadius = 0, columns = "", target = "", embedded = FALSE,
verbose = FALSE, validLib = vector(), numThreads = 4, showPlot = TRUE,
noTime = FALSE)
```

`pathIn` |
path to |

`dataFile` |
.csv format data file name. The first column must be a time index or time values unless noTime is TRUE. The first row must be column names. |

`dataFrame` |
input data.frame. The first column must be a time index or time values unless noTime is TRUE. The columns must be named. |

`pathOut` |
path for |

`predictFile` |
output file name. |

`lib` |
string or vector with start and stop indices of input data rows used to create the library from observations. Mulitple row index pairs can be specified with each pair defining the first and last rows of time series observation segments used to create the library. |

`pred` |
string with start and stop indices of input data rows used for predictions. A single contiguous range is supported. |

`maxE` |
maximum value of E to evalulate. |

`Tp` |
prediction horizon (number of time column rows). |

`tau` |
lag of time delay embedding specified as number of time column rows. |

`exclusionRadius` |
excludes vectors from the search space of nearest neighbors if their relative time index is within exclusionRadius. |

`columns` |
string of whitespace separated column name(s) in the input data used to create the library. |

`target` |
column name in the input data used for prediction. |

`embedded` |
logical specifying if the input data are embedded. |

`verbose` |
logical to produce additional console reporting. |

`validLib` |
logical vector the same length as the number of data rows. Any data row represented in this vector as FALSE, will not be included in the library. |

`numThreads` |
number of parallel threads for computation. |

`showPlot` |
logical to plot results. |

`noTime` |
logical to allow input data with no time column. |

A data.frame with columns `E, rho`

.

```
data(TentMap)
E.rho = EmbedDimension( dataFrame = TentMap, lib = "1 100", pred = "201 500",
columns = "TentMap", target = "TentMap", showPlot = FALSE )
```
