jar adds a specified number to all features of both input vectors, after which it calculates rate ratios for all features. The function was designed to prevent zeros in count data.

1 |

`t1` |
Numeric vector. Feature data in test sample |

`t0` |
Numeric vector. Feature data in control sample |

`n` |
Numeric. Specify how much is added to each value before calculating rate ratios. Default = 5 |

`log` |
Logical or numeric. Specify whether to log-transform the rate ratio, and with what base. If TRUE, uses log2. Default = TRUE |

`normfun` |
Character string. Specify with which function to standardize the data. Default = "sum" |

`normsubset` |
Integer vector. Specify the indices of features that are to be used in standardization |

Returns a numeric vector of the same length as the input vectors with the (log2-transformed) rate ratios after adding a specified number to all features.
