Prepares the data for pivotal tabulation

Description

This function prepares the data pivotal for tabulation. It is intended to use as a first step in the creation of a report pivotal table. It is not likely that this function will be used as stand-alone

Usage

table_prep(dfrm, x, y, var, fill = "", type = "latex", convchar = TRUE)

Arguments

dfrm	the data frame for which the table should be generated
x	vector of x variable(s) in the data frame
y	vector of y variable(s) in the data frame (will be cast to generate long format)
var	variable within the data frame with the values to be placed in the table
fill	character vector of one indicating the character to use in case of missing values
type	character vector of one indicating the type of table to generate, see details
convchar	logical indicating if special characters should be masked

Details

This function only prepares the data for pivotal tabulation. The base of the function is the dcast function from plyr to reshape the data and the generation of a table header object to indicate how headers should be placed within the table. The function also specifies a type argument which includes "latex" or "html", this is necessary to identify specific character handling (convchar) that differs between HTML and LaTeX.

Value

The function returns a list with the original dataframe, the table header, table data and other table specifications

data(Indometh)
table_prep(Indometh,"time","Subject","conc")
