tsum3: Table Summary 3 independent(x) variables

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")))

Arguments

d

a data.frame or matrix with colnames

y

y variable name. a continuous variable

l

a vector of two x variable name 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 summarize function names

h

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

ol1

order of levels of 1st left side x variable

ol2

order of levels of 2nd left side x variable

ou

order of levels of upper side x variable

rm.dup

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

repl

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

Value

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

Details

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