### Description

ABSDataSet object and constructors

### Usage

1 2 3 |

### Arguments

`counts` |
a matrix or table with at least two columns and one row, |

`groups` |
a factor with two groups, whose length should be equal with sample size |

`normMethod` |
method for estimating the size factors, should be one of 'user', 'total', 'quartile' and 'geometric'. See |

`sizeFactor` |
ize factors for 'user' method, self-defined size factors by user. |

`minDispersion` |
a positive double for user-defined penalty of dispersion estimation |

`minRates` |
low bounder rate of baseline estimation for counts difference, default is 0.1 |

`maxRates` |
up bounder rate of baseline estimation for counts difference, default is 0.3. Setting minRates equal with maxRates will result in a testing on user-define rate, |

`LevelstoNormFC` |
maximal level of average standard deviation in fold-change normalization according to expression level, default is 100. |

### Details

The function contructs an ABSDataSet object with counts table and groups. It also checks the structure of counts and groups.The ABSDataSet is a class, used to store the input values, intermediate calculations and results of an analysis of differential expression. It also contains information for the running time of an analysis.

### Value

An ABSDataSet object.
