ftable-matrices: Combining flattened tables.

In memisc: Management of Survey Data and Presentation of Analysis Results

Combining flattened tables.

Description

With the method functions described here, flattened (contingency) tables can be combined into more complex objects, of class "ftable_matrix". For objects of these class format and print methods are provided

Usage

## S3 method for class 'ftable'
cbind(..., deparse.level=1)

## S3 method for class 'ftable'
rbind(..., deparse.level=1)

## S3 method for class 'ftable_matrix'
cbind(..., deparse.level=1)

## S3 method for class 'ftable_matrix'
rbind(..., deparse.level=1)

## S3 method for class 'ftable_matrix'
format(x,quote=TRUE,digits=0,format="f",...)

## S3 method for class 'ftable_matrix'
Write(x,
                            file = "",
                            quote = TRUE,
                            append = FALSE,
                            digits = 0,
                            ...)
                            
## S3 method for class 'ftable_matrix'
print(x,quote=FALSE,...)

Arguments

...	for cbind and rbind methods, two or more objects of class "ftable" or "ftable_matrix"; for the other methods: further arguments, ignored.
deparse.level	ignored, retained for compatibility reasons only.
x	an object used to select a method.
quote	logical, indicating whether or not strings should be printed with surrounding quotes.
digits	numeric or integer, number of significant digits to be shown.
format	a format string as in formatC
file	character string, containing a file path.
append	logical, should the output appended to the file?

Value

cbind and rbind, when used with "ftable" or "ftable_matrix" objects, return objects of class "ftable_matrix".

Examples

ft1 <- ftable(Sex~Survived,Titanic)
ft2 <- ftable(Age+Class~Survived,Titanic)
ft3 <- ftable(Survived~Class,Titanic)
ft4 <- ftable(Survived~Age,Titanic)
ft5 <- ftable(Survived~Sex,Titanic)

tab10 <- xtabs(Freq~Survived,Titanic)

(c12.10 <- cbind(ft1,ft2,Total=tab10))
(r345.10 <- rbind(ft3,ft4,ft5,Total=tab10))

## Not run: 
tf <- tempfile()
Write(c12.10,file=tf)
file.show(tf)

## End(Not run)
