Function to obtain a matrix containing trait averages at community level.
For more details, see `syncsa`

1 |

`comm` |
Community data, with species as columns and sampling units as rows. This matrix can contain either presence/absence or abundance data. |

`traits` |
Matrix or data frame of species described by traits, with traits as columns and species as rows. |

`scale` |
Logical argument (TRUE or FALSE) to specify if the traits are measured on different scales (Default scale = TRUE). When scale = TRUE traits are measured on different scales and the matrix T is subjected to standardization within each trait. When scale = FALSE traits are measured on the same scale the matrix T is not subjected to standardization. |

`ranks` |
Logical argument (TRUE or FALSE) to specify if ordinal variables are convert to ranks (Default ranks = TRUE). |

`notification` |
Logical argument (TRUE or FALSE) to specify if notifications of missing observations are shown (Default notification = TRUE). |

`matriz.w` |
Standardized community matrix, where rows are communities and columns species. Row totals (communities) = 1. |

`matriz.b` |
Matrix of traits, exactly the same data input. |

`matriz.T` |
Matrix containing trait averages at community level. If Scale = TRUE the matrix T is standardized within the traits. |

**IMPORTANT**: The sequence species show up in community data
matrix MUST be the same as they show up in traits matrix. See
`organize.syncsa`
