Description

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

Usage

tsum2(d, y, l, u, e=c("mean", "sd", "length"), h=NULL, ol="", 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

x variable name to be shown on the left side

u

x variable name to be shown on the upper side

e

h

a vector of summarize function names for the horizontal subgroup. If NULL, it becomes same to e argument.

ol

order of levels of 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.
