Untable: Untable an Aggregated Data Frame

In SciencesPo: A Tool Set for Analyzing Political Behavior Data

Description

A method for recovering a data.frame out of summarized data, i.e. contingency table or aggregated data.

Usage

Untable(x, ...)

## S3 method for class 'data.frame'
Untable(x, freq = "Freq", row.names = NULL, ...)

## Default S3 method:
Untable(x, dimnames = NULL, type = NULL,
  row.names = NULL, col.names = NULL, ...)

Arguments

x	the table object as a data.frame, table, or, matrix.
freq	the column name of count values.
row.names	row names to add to data.frame if any.
dimnames	set the dimnames of object if required.
type	the type of variable. If NULL, ordered factor is returned.
col.names	column names to add to the data.frame.
...	Extra parameters ignored.

Examples

gss <- data.frame(
expand.grid(sex=c("female", "male"),
party=c("dem", "indep", "rep")),
count=c(279,165,73,47,225,191))

print(gss) # aggregated data.frame

# Then expand it:
GSS <- Untable(gss, freq="count")
head(GSS)

# Expand from a table or xtable object:
# Fisher's Tea-Tasting Experiment data
 tea <- table(poured=c("Yes", "Yes", "Yes", "No","Yes","No", "No", "No"),
             guess=c("Yes", "Yes", "Yes", "Yes", "No", "No","No","No"))

Untable(tea)

# Expand with a vector of weights
Untable(c(3,3,3), dimnames=list(c("Brazil","Colombia","Argentina")))
