### Description

Creates a dataset for CCRS from a preference data matrix.

### Usage

```
create.ccrsdata(X,q=q)
```

### Arguments

`X` |
An n by m categorical data matrix. |

`q` |
An integer indicating the maximum rating. |

### Details

For the difference between Mmat.q and Mmat.q1 in the resulting list, see Section 3.2 in reference paper.

### Value

Returns a list with the following elements.

`Fmat` |
An n by q-1 matrix of scaled rank-ordered boundary data. |

`Mmat.q1` |
A q-1 by 3+1 matrix of I-spline basis functions, evaluated at the boundaries. +1 indicates all 0 intercepts. |

`Mmat.q` |
A q by 3+1 matrix of I-spline basis functions, evaluated at the midpoints between boundaries. |

`X` |
