In epiDisplay: Epidemiological Data Display Package

Summary with graph

Description

Summary of data frame in a convenient table. Summary of a variable with statistics and graph

Usage

summ(x, ...) 
## Default S3 method:
summ(x, by=NULL, graph = TRUE, box = FALSE, pch = 18, 
    ylab = "auto", main = "auto", cex.X.axis = 1, cex.Y.axis = 1,
    dot.col = "auto", ...)
## S3 method for class 'factor'
summ(x, by=NULL, graph=TRUE, ...)
## S3 method for class 'logical'
summ(x, by=NULL, graph=TRUE, ...)
## S3 method for class 'data.frame'
summ(x, ...)

Arguments

x	'x' can be a data frame or a vector
by	a stratification variable, valid only when x is a vector
graph	automatic plot (sorted dot chart) if 'x' is a vector
box	add a boxplot to the graph (by=NULL)
pch	plot characters
ylab	annotation on Y axis
main	main title of the graph
cex.X.axis	character extension scale of X axis
cex.Y.axis	character extension scale of Y axis
dot.col	colour(s) of plot character(s)
...	additional graph parameters

Details

For data frames, 'summ' gives basic statistics of each variable in the data frame. The other arguments are ignored.

For single vectors, a sorted dot chart is also provided, if graph=TRUE (default).

Examples

data(Oswego)
.data <- Oswego
summ(.data)
with(.data, summ(age))
with(.data, summ(age, box=TRUE))
with(.data, summ(age, dot.col="brown"))
with(.data, summ(age, by=sex))
# Changing dot colours
with(.data, summ(age, by=sex, dot.col = c("blue","orange")))
# Enlarging main title and other elements
with(.data, summ(age, by=sex, cex.main=1.5, cex.X.axis=1.5, cex.Y.axis=1.7))

# Free vector
summ(rnorm(1000))
summ((1:100)^2, by=rep(1:2, 50))
summ((1:100)^2, by=rep(c("Odd","Even"), 50), main="Quadratic distribution by odd and even numbers")
