tsum2: Table Summary with 2 independent (x) variables

In sasLM: 'SAS' Linear Model

Table Summary with 2 independent (x) variables

Description

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

Usage

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

Arguments

d	a data.frame or matrix with column names
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 summary function names
h	a vector of summary function names for the horizontal subgroup. If NULL, it becomes the same as the e argument.
ol	order of levels of the 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.

Details

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

Value

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