table_two_by_two: Creates tables for baseline characteristics or similar tables

In csmoxford/prettyTables: Pretty tables

Description

Provide summary statistics on two or three variables. Rows consist of two variables to summaries and columns may consist of an optional stratification variable. There is also an option to print an overall column alongside the stratified summaries.

Usage

table_two_by_two(data, var, var2, var.name = NULL, var.name2 = NULL,
  var.order = NULL, var.order2 = NULL, type, strata = NULL,
  strata.names = NULL, strata.count = TRUE, overall = TRUE, count = "n",
  round = 3, messages = TRUE, zeros = FALSE)

Arguments

data	Dataset to generate table from
var	A character string naming the row variable to stratify by
var2	A character string naming the variable to summarise over
var.name	Optional. A formatted version of var
var.name2	Optional. A formatted version of var2
var.order	Optional. A vector of the values of var in the order you want to display them
var.order2	Optional. A vector of the values of var2 in the order you want to display them. Note that this creates empty rows when there are no values for a given variable.
type	A vector of the method to summarise var2
strata	A string of the column to used to stratify on
strata.names	Otional. A named vector of alternative strata names
strata.count	TRUE/FALSE for displaying strata counts at the top of each column
overall	TRUE/FALSE for including an overall column
count	"n","miss" or "none" providing the counts, missing values or omitting for each column for numeric variables
round	A value or vector for the number of significant figures to report the data to
messages	TRUE/FALSE report messages for missing row names in var.order
zeros	TRUE/FALSE whether to print zeros if none are found defaults to FALSE.

Details

Available methods and values for Type:

"miqr"	median (Q25,Q75)
"miqrr"	median (Q25,Q75)[min,max]
"mrng"	median (Q0,Q100)
"avsd"	mean (sd)
"avci"	mean (confidence interval)
"st"	count
"str"	count/total
"stp"	count (percent)
"strp"	count/total (percent)

Value

Returns a data.frame

Examples

# Data
data(iris)

# This function does not work with factors so convert to string.
iris$Species=as.character(iris$Species)

# generate a variable to stratify by since iris only has one target
# stratification
iris$Petal.split="Short"
iris$Petal.split[iris$Petal.Length>4.3]="Long"

# build the table
table_two_by_two(iris, var="Species",var2="Sepal.Length",
var.name2="Sepal Length", type="miqr",strata="Petal.split", round=1)
