Creates an object of the `accrued`

class for use in the plot, summary, and error functions in the accrued package.

1 | ```
data.accrued(data, start = NULL, final = NULL)
``` |

`data` |
A matrix of time series data, with rows as consecutive encounter dates and columns as accrual lag. |

`start` |
The start date. If none is specified it defaults to 1. |

`final` |
Vector of final counts for each encounter date. If omitted, the final column of |

The function converts a matrix of patrically accrued counts into an `accrued`

object.
The value at the *i*th row and *j*th column of `data`

represent the count for encounter
date *i* as known *j-1* days after the encounter date. If `final`

is not specified,
the last column of `data`

is used as the final count.

Summary and plot methods exist for objects of this class. Several additional graph types are available, including `barcode`

, `uploadPattern`

,
`laggedTSarray`

and `lagHistogram`

.

`data.accrued`

returns an object of the `accrued`

class.

An object of the `accrued`

class is a list containing the following components:

`final ` |
Vector of final counts |

`data ` |
Matrix of counts. The value at the |

`start ` |
List of boolean start variable and start date |

Print, summary and plot methods exist for objects of the `accrued`

class.
