tsum2 | R Documentation |

Summarize a continuous dependent(y) variable with two independent(x) variables.

tsum2(d, y, l, u, e=c("Mean", "SD", "N"), h=NULL, ol="", ou="", rm.dup=TRUE, repl=list(c("length"), c("n")))

`d` |
a data.frame or matrix with colnames |

`y` |
y variable name. a continuous variable |

`l` |
x variable name to be shown on the left side |

`u` |
x variable name to be shown on the upper side |

`e` |
a vector of summarize function names |

`h` |
a vector of summarize function names for the horizontal subgroup. If |

`ol` |
order of levels of left side x variable |

`ou` |
order of levels of upper side x variable |

`rm.dup` |
if |

`repl` |
list of strings to replace after summarize. Length of list should be 2, and both should have the same length. |

A convenient summarization function for a continuous variable with two x varaibles; one on the left side, the other on the upper side.

A data.frame of summarized values. Column names are from the levels of `u`

. Row names are basically from the levels of `l`
