Description

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

Usage

tsum3(d, y, l, u, e=c("Mean", "SD", "N"), h=NULL, ol1="", ol2="", ou="", 
        rm.dup=TRUE, repl=list(c("length"), c("n")))

Value

A data.frame of summarized values. Column names are from the levels of u. Row names are basically from the levels of l.

Arguments

d

a data.frame or matrix with column names

y

y variable name, a continuous variable

l

a vector of two x variable names to be shown on the left side. The length should be 2.

u

x variable name to be shown on the upper side

e

a vector of summary function names

h

a list of two vectors of summary function names for the first and second horizontal subgroups. If NULL, it becomes the same as the e argument.

ol1

order of levels of the 1st left side x variable

ol2

order of levels of the 2nd left side x variable

ou

order of levels of the upper side x variable

rm.dup

if TRUE, duplicated names of levels are specified on the first occurrence only.

repl

a list of strings to replace after summarization. The length of the list should be 2, and both elements should have the same length.
